INTRODUCTION

SUMMARY OF RESULTS

4.

Exploration in 1987/88 comprised

a UTEM survey over the Anomaly 1 area.

Petrographic and geochemical characterisation of a suite of

Beulah rocks.

The Beulah volcanics are calc-alkaline Mount Read Volcanics.

No rocks had early Cambrian tholeiitic characteristics.

A lead isotope study of high lead areas in the Beulah basalt

andesite and of barite occurrences adjacent to the Beulah

Licence.

No prospective liTEM conductors in the geochemical Anomaly 1

(Sharman's grid) area.

Lead isotopes suggest the the Beulah barite and the Paradise

barite are vein type but not Devonian granite related. High

lead in Beulah andesite has a Cambrian Mt. Read volcanogenic

massive sulphide signature.

A zone of high Zn in Beulah basalt - andesite was found.

Possible Hellyer type hangingwall alteration at Beulah barite

projects onto the Beulah Licence.

Samples at "Anomaly 1" in the Beulah basalt and near Star of

the West in Minnow Keratophyre to the south did not contain

gold levels above detection limit.

The licence should be renewed.

A soil sampling programme should be conducted on the

alteration trend from the Beulah barite onto the Beulah

Licence.

Alteration in CRA holes to the south should be examined and

compared with surface samples.

4. GEOLOGY

Regional descriptions of the geology are included in Aberfoyle's

1987 Annual Report. Aberfoyle's 1987/88 programme aimed to compare

the Beulah volcanics with Cambrian volcanics elsewhere.

Petrographic descriptions by Dr. ~ Crawford and Mr. D. Cowan are

included as Appendices II and III. Grid co-ordinates and field

sample descriptions are attached as Appendix I. Sample locations

are plotted on Figure 4 in a pocket at the back of this report.

It is concluded by the author (DJJ) that the lavas and lava

breccias at Beulah are similar to the Que-Hellyer andesites.

Petrographically the similarities include the abundance of perlitic

glass in many of the lavas, abundant albite phenocrysts, pyroxene

phenocrysts, the inclusion of dacitic units and rock fragments in

the volcanic pile and the occurrence of a polymict component in the

IIIIIIIIIIIIII

5.

786009

9.

lavas. Metamorphic minerals include epidote prehnite and

pumpellyite, but grades are not high enough to develop amphibole.

These prehnite pumpellyite facies grades are similar to those in

the Que Hellyer volcanics and contrast with the higher grade

Western Sequence rocks of the Queenstown area.

The Beulah lavas are petrographically distinct from the Crimson

Creek type lavas snch as those ascribed to the Motton Spilite north

west of Beulah.

No systematic field mapping was carried out in this year's

programme, however the gradational contact between the Beulah

formation and the Gog Range Greywacke is apparent by intercalation

and mixing both on a macroscale and microscopically. This occurs

in the area north and south east of the Beulah barite

occurrence where a soil sampling programme is planned.

Immobile Elements

Ternary plots of the immobile elements Ti, Zr and Yare

presented as figures 4 to 6 where they are compared with Cambrian

volcanics elsewhere in Tasmania. Clearly the Beulah volcanics

are calc-alkaline and fall within the field for the Mount Read

Volcanics as reported by McClenghan and Corbett (1986) (Figure

4). They also cluster in the ,field for footwall andesites and

hangingwall andesite-basalts at Hellyer (Jack unpublished

data) (Figure 5). This accords with their petrographic

similarity with footwall andesites. They are clearly neither

ocean floor nor within plate lavas, (Figure 6) and are very

different to Crimson Creek related Cambrian lavas.

Other Characteristics

Other characteristics similar to the Que-Hellyer volcanics are

the high K20 levels (up to >4% K20), and MgO levels similar to

the Hellyer footwall andesite.

Figure 7a shows a clustering of the Beulah barite and Beulah

basalt samples on a Pb208/Pb204 vs Pb206/Pb204 plot.

Figure 7b compares the results at Beulah with those reported in

Gulson, Large and Porritt 1987. While the lead in the Beulah

lavas plots close to that at Rosebery and is interpreted to be

volcanogenic Rosebery type, the samples at the Beulah barite

occurrence can be interpreted as Cambrian vein type. It is

significant that none of the samples plot in the Devonian

granite related fields. This "older" less radiogenic lead at

Beulah is considered to be a positive feature.

Anomaly 1 area

The high lead values obtained in the Anomaly 1 area were

repeated. A suite of samples from the Anomaly 1 area, many

with associated haematite and manganese were analysed for

gold. No gold values were reported.

Bend in road area

An assay of 750 ppm Zn, from north of the Beulah barite

occurrence, along the trend of hangingwall alteration

interpreted in CR)(s drilling requires further investigation.

Sericite and chlorite alteration are described in this rock,

(sample no. 334714). The possibility that the elevated Zn may

be due to adsorption by manganese will be tested by

correlating Zn and Mn values in a suite of samples.

Beulah Barite

This is outside the licence area but was sampled for lead

isotope analysis. A maximum of 2.68% Pb and 153 ppm Ag

occurred in massive white barite. Other barite contained

negligable Pb and Ag. Gossan adjacent to the barite contained

variable Pb (20 ppm and 245 ppm). No Au was reported.

Paradise Barite

Also outside the licence, the old trench over this occurrence

was located and sampled. The assays were anomalous in copper

(up to 610 ppm Cu) and contained low overall Pb and Zn. The

rhyolite host and quartz iron oxide gossan were submitted for

lead isotope analysis.

Stonebridge Gossan

Also just outside the licence area, maximum assays of 2.17%

Pb, 42 ppm Ag, 950 ppm Cu and 850 ppm Zn were obtained. The

metal ratios suggest a different style of mineralisation to

that at the nearby Paradise barite.

Star of the West (old gold prospect)

No gold values were reported from samples taken in the -80

metre long "Star of the East" adit.

6. GEOPHYSICS written and interpreted by Jovan Silic

Geochemical Anomaly 1 (Sharman-s Grid) liTEM Survey

Considering that the strike orientation of any possible

mineralisation at depth was not precisely known, two grids at right

angles to each other were surveyed (Figure 8).

The collected data is generally of a good quality, despite the fact

that numerous fences and some power lines are present in the area.

Although some surficial and lithological conductors are evident in

the data, as are responses due to some fences, no response that can

be attributed to an accumulation of massive sulphides at depth can

be interpreted (see UTEM data, Appendix VI).

7. CONCLUSIONS

A volcanogenic hydrothermal system operated at Beulah where

characteristic Mount Read Volcanics are confirmed to occur.

The possibility that the Cambrian volcanics at Beulah are

tholeiitic Crimson Creek type lavas or that all the

mineralisation in the area is related to Devonian granite

intrusions has been discounted.

Summary

Sample 271707a represents a distinctive, relatively quite unaltered

olivine basalt with Tertiary characteristics and apparerntly unrelated

to the other basics in this suite.

Eight rock chip samples from the Beulah area near Sheffield (Tas.) were

received for petrological examination. Representative thin-sections were

examined in oblique incident and transmitted light, and are detailed in

the attached descriptions.

33.

78G033

REPORT CMS 88/1/2

Sample 271708c is similarly distinctive, representing a quartz-mica

barite(-carbonate)-altered tuffaceous argillite with rhyolitic clastic

debris. Alteration in this rock may be broadly compared with that in

certain minor baritic acid volcanics, for example at Que River, but

is ooorly diagnostic as to whether volcanohydrothermal or granitic in origin.

The bulk of this suite comprises altered, variably sheared and variably

weathered and ferruginised labile sedimentary rocks and altered basic

volcanics. These two groups ("greywackes" and Beulah Basalt) are conceivably

intercalated. Relatively fresh basalts carry conspicuous opaques. Sediments

are basic-volcanomict in part and may carry degraded primary hematite.

Both groups may exhibit phyllosilicate alteration, although basics also

include saussurite-uralite and epidote-prehnite-pumpellyite alteration

assemblages.

Petrological Descriptions

(T .5. 59545)This may be categorised as a ferruginous clay rock representingan altered, weathered and ferruglnised labile turbiditiclithoclastic sediment. It exhibits a relict framework ofdegraded/ferruginised lithic clasts, poorly sorted in the sandto grit range, with angular/subangular shapes modified by asecondary dimensional orientation in response to mildshearing effects and best examined in oblique incident light.A rather prominent matrix (hence turbiditic) exhibits a weakphyllitic fabric. Clastic and particularly matrix componentsare largely represented by fine-graineo phyllosilicate aggregateswhich are indeterminate due to marked limonitic Fe-stainingpartly derived from ultra fine hematite.

A few clasts are represented by random to incipientlyorientated sericite aggregates. These may include accessoryanhedral quartz and appear to represent selectively sericitisedfelsic types. The majority of clasts exhibit oxidised andleucoxenised fine accessory opaques and are interpretedas basic volcanic-derived. Accessory clastic components includesilt- to fine sand-sized quartz grains and argillised-silicifiedfeldspar grains.

The major phyllosilicate phase in this rock was possiblychlorite and may have been low-grade metamorphic in origin.Finer detail is obscured by the marked ferruginisation.

(T .5. 59546)This ferruginous clay rock represents a weathered andferruginised low-grade metapelite and consists largely ofheavily iron-stainedf, fine-grained, phyllitic-microtexturedphyllosilicate aggregates. Traces of orientated semi-sericiticwhite mica are present, but the major phase was possiblychloritic. Accessories comprise thinly dispersed relictdetrital silt-sized quartz grains and oxidised/leucoxenisedopaques.

This rock exhibits alteration and veining features. Irregularto lensoid zones and discordant veinlets of fine-grained,rosette-textured, extensively degraded (illitised/ferruginised)white mica are present. These are concentrated in the host rock,but also appear in an irregular centimetric-scale mass ofstressed vein-type quartz in marginal zones, where they appearto represent intraclasts.

786035

Stress effects evidently post-date the phyllitic tectonicfabric (host rock), which is locally mildly contorted andsemi-brecciated.

(T .5. 59547)This sample represents an essentially fresh, weakly amygdaloidaloli vine basalt.

Apart from development of amygdales and the semi-pervasivemontmorillonite mesostasis, this rock is unaltered. Generalfeatures are consistent with a Tertiary basalt.

35.CMS 88/1/2Page 2

Vein-quartz aggregates are pervaded by secondary intergranularpatches of microcolloform limonite and Mn-oxide, possibly aftercarbonate in the absence of diagnostic pseudomorphs or boxworks.Minor manganiferous limonite pseudomorphs after fine-grainedpyrite (and ?arsenopyrite) are present.

Frequent single to clustered phenocrysts (to 500 urn) and microphenocrysts of olivine are enclosed in a basaltic-texturedgroundmass of slightly felted labradorite microlaths withinterstitial olivine granules and minor pale brown augite.A patchy montmorillonitic mesostasis is present. Minoramygdales consist of poorly twinned albite or locally calcite.Conspicuous accessory flaky ilmenite, supplemented by a littlemagnetite, is present.

(T.S. 59548)This rock may be categorised as an altered tuffaceous argillite,consisting essentially of a loose framework of psammitictuffaceous debris in a cherty argillitic matrix.

The matrix is weakly banded and consists of semi-sericiticwhite mica and microcrystalline quartz with pervasive finesilt-sized clastic white mica flakes, supplemented bythinly disseminated silt-sized quartz grains. In contrast tothe lithic clasts and feldspar grains, the matrix is unaltered,although thin, irregular barite veinlets occur sporadically.These veinlets are locally displaced by sporadic sericiticfoliae reflecting incipient shearing effects .

Clasts are dominated by quartz crystals and fragments,with occasional classical embayed euhedra. Subordinate similarlysized feldspar grains and poorly determinate lithic clasts.These "labile" components are selectively replaced byaggregates of fine to microgranular quartz and fine to semisericitic muscovite with varying proportions of barite.Accessory clastic leucoxenic semi-opaques are present.

This rock is flow-structured and weakly flow-brecciated, withorientated laths and amygdales and occasional intraclasts.

(T.S. 59549)This sample represents an altered basaltic amvodaloidal lava.

This rock is only incipiently flow-structured. Phenocrysts arerather evenly distributed and, dependent on field relationships,the rock could be interpreted as a semi-chilled minor intrusive.

CMS 88/1/2Page 3

The conspicuous phenocrysts comprise variably sericitised/zoisitic epidote-stained labradorite (weakly zoned), withsubordinate green uralitic amphibole-pseudomorphed orthopyroxene,fresh pale green augite, and relatively quite minor greenhornblende. The groundmass comprises random to flow-orientatedplagioclase microlites with a felsic mesostasis and conspicuousfine primary magnetite.

Accessory fine-grained carbonate, represented by limoniticpseudomorphs, accompanies the replacive sericite-mica-bariteaggregates. There is no positive evidence of (oxidised) sulphide.

The rock is strongly porphyritic in epidote-stained/sericitepseudomorphed feldspar with subordinate fresh pale greenaugite and incipiently chloritised green hornblende. Thegroundmass comprises similarly altered random feldsparmicrolaths with subordinate pyroxene and amphibole laths witha sericitised and cloudy epidote-stained, primarily glassy?mesostasis. Conspicuous fine primary accessory magnetiteis present.

Major constituents comprise altered plagioclase and subordinatealtered pyroxene laths in a pervasively ultra finely hematiticsubvitric groundmass. Plagioclase is represented bypseudomorphous aggregates of microcrystalline cloudy epidoteand sericite ("saussurite") and pyroxene by relatively massivecloudy epidote, with subordinate cillorite and pumpellyite.Sporadic to locally conspicuous amygdales consist of quartz,albite and chlorite in varying proportions with locallyconspicuous calcite, accessory epidote and pumpellyite, andtraces of prehnite.

(T.S. 59551)This rock is similar to 271710b, but may be classified as amoderately altered basalt.

(T.S. 59550)This is an altered basic-intermediate volcanic, reasonablyclassified as an andesite, although primary mineralogy ispartly obscure.

Sporadic films and spongy semi-massive zones of Mn-oxideimpregnate this limonitic/argillaceous weathered rock.

Alteration is analogous to that in 271710b; less advanced interms of alteration of feldspar, but complexed by uralitedevelopment. This is essentially a reflection of the relativelymafic primary composition.

(T .5. 59552)This is a ferruginous clav rock similar to 271705b, butinterpreted as an altered, mildly sheared and thoroughly weathered/ferruginised basic volcanic on the basis of relict features.

The rock consists essentially of ferruginised clay aggregatesas a matrix to pervasive aggregates (mean 250 urn to 750 urn)of degraded/illitised, fine-grained white mica with accessorymicrogranular quartz. These features have the appearance ofpseudomorphed phenocrysts. Relatively ferruginous, lensoidto subprismatic, similarly sized clay aggregates are similarlyinterpreted.

Three samples (Nos. 271770, 271772, 271775) were received for petrographicstudy; thin-sections were prepared, and offcuts were subjected topotash stain tests.

These two rocks are closely similar and are intrusive porphvritic rhyolites;the main difference is that 271775 is more extensively weathered (thoughstill relatively fresh) and is goethite-veined.

The original rock was coarsely laminated or banded, with alternatingbands of argillite and micaceous siltstone; evidently, the argillitewas more competent during shearing, and was stretched and fractured(boudinaged), whereas the siltstone behaved incompetently, and deformedplastically, resulting in a semi-schistose rock. The argillite too,is semi-schistose and finely crenulated in places. Clearly, there is noresemblance between this rock and 271770/271775.

PETROGRAPHIC REPORT

Rocks from Henty Fault Wedge. Anthony Road and the Beulah Area

For Aberfoyle Exploration Ud. 15/2188

by

Anthony J. Crawford

Geology Department

University of Tasmania

SUMMARY: This rock is a reddish, highly-altered phenocryst-rich meta-andesite in

which large plagioclase phenocrysts are totally sericitized and less abundant former

mafic phenocrysts (augite?) are variably altered to chlorite, epidote, Fe oxide and

minor sericite.

DESCRIPTION:

Phenocrysts'

This rock is highly porphyritic, with approx.. 35 modal % of altered plagioclase euhedra

to 4mm long and sparse fonner mafic phenocrysts now altered to chlorite-dominated

assemblages. The large plagioclase phenocrysts are totally replaced by felted masses

of colourless sericite and less abundant pale green chlorite, which have completely

obliterated former zoning and twinning. Sparse former· mafic phenocrysts are often

aggregated together, and have crystal shapes most reminiscent of augite. They are

now replaced by pale green chlorite and foxy red oxychlorite (or ferri-stilpnomelane?).

Groundmass:

The dark groundmass of this lava is microcrystalline to glassy and charged with

plagioclase microlites and microphenocrysts which are also totally sericitized. Fonner

glass is replaced by almost isotropic, red-brown Fe oxide-dominated alteration

products which impart the reddish colour to this lava. A locally-developed streaky

schistosity is defined by sericite and chlorite in places, and irregular patches of

secondary quartz and minor epidote occur throughout the groundmass. The

metamorphic mineral assemblage is probably remnant prehnite-pumpellyite or lower

greenschist facies, but has been overprinted and almost obliterated by the sericite and

Fe-oxide producing oxidation (weathering?) event.

SUMMARY: This rock is a slightly-altered, autobrecciated phenocryst-rich acid

meta-andesite or mata-dacite composed of dark, quenched glassy fragments in a

'matrix' of lighter coloured, more slowly-cooled lava.

DESCRIPTION:

This rock is clearly a dark lava breccia in handspecimen, with fragments to at least 4

em long. In the thin section prepared, two fragment types are present, a distinct, mildly

vesicular lava charged with plagioclase phenocrysts in a very dark glassy ground

mass, and lighter coloured, more diffuse 'fragments' or areas also with plagioclase

phenocrysts but with microcrystalline rather than glassy groundmass.

Phenocrysts:

In the dark fragments, plagioclase phenocrysts are albitized euhedra to 0.5 mm long

containing specks of sericite and minor chlorite. Twinning, and rows of devitrified glass

inclusions parallel to crystal edges are commonly preserved. Former mafic pheno

crysts are rare, and totally chloritized. It is difficult to state with certainty whether these

were formerly clinopyroxene (augite) or orthopyroxene, although for the following

reasons I tend to favour the latter

1). crystal shape is more typical of orthopyroxene,

2). the fact that in modern orogenic andesite-dacite series rocks, orthopyroxene

generally appears in the crystallization sequence at about the dacite stage of

differentiation, and

3). in rocks of this metamorphic grade, augite is usually preserved unaltered.

Groundmass:

The groundmass of these dark coloured fragments was formerly glassy and slightly

vesicular. Vesicles and fractures are filled with pale green chlorite and are lined by

secondary quartz. Diffuse patches of pale, non-pleochroic prehnite permeate the dark

groundmass, and small patches of higher relief, golden epidote and deeper green

pumpellyite also occur. Prehnite also occurs as vein fillings and includes small perfect

euhedra of quartz. Metamorphic grade is clearly prehnite-pumpellyite facies.

The lighter coloured areas of this rock differ in only two respects from the dark

fragments; they contain sparse fresh augite phenocrysts notably larger (to 0.5mm) than

those mafic pseudomorphs in the dark fragments, and the groundmass in the lighter

areas is microcrystalline rather than glassy as in the dark fragments. Boundaries

between the light and dark fragments are sharp but highly irregular with the light areas

tending to wrap around the dark fragments. It is suggested that this rock represent an

andesitic to dacitic lava flow which quenched at the flow surface to form the dark,

glassy lava represented by the dark fragments in this rock; as eruption continued,

fragments of the glassy surface of the flow were turned over into the less rapidly cooled

interior portion of the flow, now represented by the lighter areas of this rock.


(

n I;..~. .- . 786044

SUMMARY: This rock is an autobrecciated phenocryst-rich acid meta-andesite or

meta-dacite composed of dark, quenched glassy fragments in a 'matrix' of lighter

coloured, more slowly-cooled lava. It is virtually identical to 334715.

DESCRIPTION:

In most respects this rock is identical to 334715, except that darker fragments (some

texturally intermediate between the dark and light coloured fragments described in

334715) are more abundant in this slide, and that epidote is more abundant in this rock

than 334715. Epidote occurs as small high relief euhedra growing in pale green

chlorite patches within the microcrystalline to glassy groundmass. Prehnite occurs as

large patches intergrown with quartz and pumpellyite is restricted to tiny apple green

blebs in albitized plagioclase phenocrysts. Sparse former mafic crystals are

pseudomorphed by green chlorite, and were probably orthopyroxene.


"(

SAMPLE: 334716


786045

45.

SUMMARY: This rock is a dark coloured, autobrecciated phenocryst-rich mafic

meta-andesite in which primary augite phenocrysts are preserved and the only

significant difference between fragments is a slight variation in the grainsize (glassy to

microcrystalline) of their groundmass. It is suggested that this rocks represents a single

eruptive unit in which quenching, and turning over within the flow led to the highly

variable groundmass texture of individuai fragments.

DESCRIPTION:

Phenocrvsts:

The rock contains approx. 40% phenocrysts, made up of about 30% plagioclase

phenocrysts and 10% large augite phenocrysts. Plagioclase phenocrysts are

subhedral to euhedral prisms to 1mm long; all have been albitized and many are

extensively to totally replaced by very fine-grained sericite-chlorite intergrowths

containing small globular clusters of deeper green pumpellyite and colourless, low

relief prehnite. Clinopyroxene (augite) phenocrysts are slightly rounded equi

dimensional to elongate euhedra usually showing growth twinning and often occurring

in pairs or glomeroporphyritic clots; they are fractured but essentially unaltered, and

compositional zoning is preserved in some crystals.

Groundmass:

The most striking feature of this rock is the remarkable variation in grainsize and

appearance of the groundmass, even on the scale of a single thin section. In some

areas, the groundmass is almost black, formerly glassy and charged with vesicles

which are filled by green chlorite (and occasionally yellow fibrous epidote) and lined

by beads of quartz; in some areas this glass has devitrified to a mosaic of granular

quartz and chlorite flakes. In other areas the groundmass is more crystalline, with

micro lites of plagioclase and tiny spheroidal particles of leucoxene after FeTi oxides, in

a mesostasis less dark than the glassy areas.

significant difference between fragments is a slight variation in the grainsize (glassy to

DESCRIPTION:

This rock is identical to the previous sample (334717) in every way except that it

shows some slight alteration and oxidation of the dark, formerly glassy groundmass

areas, so that these are reddish-brown in this rock, rather than nearly black as in

334717. It is so similar to 334717 that I suggest it represents part of the same eruptive

unit.

SUMMARY: This rock is a dark coloured. highly porphyritic, vesicular mafic meta

andesite or metabasalt in which primary augite phenocrysts are preserved. plagioclase

phenocrysts are highly altered and the originally glassy groundmass has devitrified.

DESCRIPTION:

Phenocrvsts:

Large euhedral to subhedral of phenocrysts of augite to 2mm long (about 5 modal

%) are strongly fractured. but alteration is limited to minor chlorite development along

fractures and cleavage planes; they often contain rounded inclusions of FeT! oxide.

More abundant (20 modal %) plagioclase phenocrysts are up to 2 mm long and are

albitized but usually extensively replaced by sericite and chlorite mats with minor deep

green granules of pumpellyite. Notable are sparse but distinctive large (to O.4mm

across) FeT! oxide microphenocrysts which are mainly replaced by leucoxene.

Groundmass:

The groundmass of this rock was originally glassy to very finely microcrystalline.

Devitrification of glass has produced ragged patches of green chlorite and small grains

and granular mosaics of secondary quartz. Leucoxene granules after FeT! oxide

grains are scattered through the groundmass.

SUMMARY: This rock is a well-preserved grey quartz- + feldspar-phyric rhyolitic lava

with a devitrifiad formerly glassy groundmass. It is one of the best preserved acidic

rocks I have seen from the Cambrian of westem Tasmania

DESCRIPTION:

Phenocrvsts:

Slightly rounded euhedral quartz phenocrysts (10 modal %) to 5mm diameter show

occasional embayments and rounded brownish melt inclusions, and are very slightly

strained. Many quartz phenocrysts are aggregates of two or three grains with intimately

sutured common boundaries. Albite phenocrysts are slightly less abundant than

quartz phenocrysts and are mainly compound grains with either euhedral of fractured

outlines; alteration is limited to minor sericite speckling and some patchy recrystall

ization to a fine-grained mosaic of secondary albite (and quartz?). Rare mafic pheno

crysts were almost certainly biotite, but have have been pseudomorphed by green

biotite.

Groundmass:

The formerly glassy groundmass of this rock has devitrified and crystallized to an

even-grained mosaic of quartz, albite and K feldspar, with minor green chlorite flakes

and epidote and pumpellyite granules. Occasional patches of myrmekitic or grano

phyric quartz-feldspar intergrowths in the groundmass probably developed during

devitrification.

SUMMARY: This rock is a phenocryst-rich metabasalt or mafic meta-andesite with a

distict brownish colour in handspecimen due to oxidation of abundant FeT!-oxide

grains in the groundmass. Phenocrysts were plagioclase and augite, although both

these phenocryst phases have been pseudomorphed by secondary minerals.

DESCRIPTION:

Phenocrysts: The most abundant phenocrysts (around 30 modal %) were calcic

plagioclase euhedra to 1mm long. These have been albitized and also partially

replaced by tiny grains of epidote, pumpellyite and chlorite. Former augite

phenocrysts, typically equidimensional euhedra to 2mm long, constitute only about 3

modal % of the rock and are always altered to a diverse suite of secondary minerals;

most are faithfully pseudomorphed by a granular mosaic of albite and yellow epidote

with minor chlorite, while others are replaced by unusual aggregates composed of

intergrown sheaves of anomalous blue and pale yellow birefringent chlorite. The latter

group invite speculation that these were formerly orthopyroxene phenocrysts; however,

their crystal shapes and the fact that they often contain small, subrounded FeT! oxide

grains are more reminiscent of typical augite phenocrysts in basalts.

Groundmass: The groundmass of this lava, although holocrystalline, is fine-grained

and characterized by microlites of albitized plagioclase and abundant grains (to O.4mm

across) of FeT! oxide, which give the rock its dull red-brown colour in handspecimen.

Within the groundmass are abundant irregular patches of beautiful pale green to clear

pleochroic sheaves and fans of pumpellyite and rosettes and smaller patches of

secondary quartz.

The alteration assemblage in this metabasic lava is albite-chlorite-epidote

pumpellyite-quartz, and very rare needles of pale grren actinolite in albite-chlorite

pseudomorphs after augite indicate that the metamorphic facies represented by this

lava straddles the lowermost greenschist -upper prehnite pumpellite facies boundary.

It is noticeable that the pumpellyite in this slide is significantly less green pleochroic

(usually meaning less Fe-riCh) than in the previous two slides; as pumpellyite normally

becomes less Fe-rich with increasing grade of metamorphism, this is in keeping with

the appearance of actinolite in this slide and its apparent absence in the other two.

SUMMARY: The rock is a strongly porphyritic mafic mata-andesite or metabasalt with

an originally glassy to microcrystalline groundmass in which primary augite pheno

crysts are preserved but former plagioclase phenocrysts have been extensively

replaced by epidote and pumpellyite.

DESCRIPTION:

Phenocrvsts;

Clinopyroxene (augite) phenocrysts are subhedral to euhedral equidimensional to

somewhat elongate prisms from 0.2 -2 mm long. They constitute around 10-15% of

the rock and are typically extensively fractured. They often contain subrounded

inclusions of FeTi oxide grains and occasional former melt inclusions are replaced by

chlorite and pumpellyite.

Calcic plagioclase phenocrysts were originally stubby to elongate prisms less than

2mm long, but have been totally replaced by a variety of alteration minerals which

show patchy development throughout the rock. Most calcic plagioclase grains were

variably albitized during low-grade burial metamorphism, and Ca and AI released was

relocated in epidote and pumpellyite, which sometimes perfectly pseudomorphs former

plagioclase phenocrysts, whereas in other places these secondary minerals form

aggregates and irregular patches in the groundmass. Most former calcic plagioclase

phenocrysts are now albite containing abundant tiny grains of pale green pumpellyite

and occasional specks and streaks of sericite.

Sparse euhedral phenocrysts to 1mm long are totally replaced by a mosaic of quartz

and chlorite and are surrounded by clouds of very fine-grained Fe-oxides. While it is

impossible to know for certain the original identity of these crystals, I suggest that they

were originally olivine, based on analogous alteration observed in other lavas, in

which occasional grains of olivine have been preserved.

Groundmass:

The groundmass of this lava was originally microcrystalline to glassy. Remnant

patches of partially devitrified pale brown glass are preserved, and in other areas a

very fine mosaic of quartz, chlorite, FeTi oxide dust and epidote-pumpellyite group

minerals have crystallized from former glass.

Metamorphic Grade and Alteration: 52.

The metamorphic assemblage represented in this rock is albite-epidote-ehlorite

-pumpellyite- quartz; minor prehnite is possibly present in the form of dirty brown dusty

patches adjacent to pumpellyite and chlorite. This assemblage is typical of the

prehnite-pumpellyite facies of regional burial metamorphism of basic rocks; the

absence of secondary actinolite or hornblende is strong evidence that this rock was

probably never heated above 3000C. the lower limit of the greenschist facies, and in

this respect it contrasts with many basalts from the Western Volcanic Sequence in the

Queenstown area. where secondary amphibole is abundant.

SUMMARY: In handspecimen, a pronounced volcanic breccia texture is defined by

fragments to more than 1Qcm long; most fragments are dark, fine-grained lava,

although a few are lighter coloured, possibly tuffaceous clasts. The rock is an

autobrecciated meta-andesite with a few exotic 'clasts' probably picked up during

eruption and flow; it has been metamorphosed to prehnite-pumpellyite facies, but

concentration of metamorphic fluids along fragment margins has produced more

intense epidote-rich stringers and patches.

DESCRIPTION:

The brecciated nature of this sample is still evident in thin section, although not as

obvious as in the hand-specimen. Most fragments appear to be of the one lava type, a

dark, mafic phenocryst-poor pilotaxitic textured andesite with the flow-texture defined

by abundant albitized plagioclase phenocryts and microphenocrysts always less than

1mm long; many of these contain patchy distributions of tiny grains of pale yellow

epidote, green pumpellyite and chlorite, and sometimes minor sericite. The ground

mass was glassy in some fragments (glass now replaced by a quartz-chlorite mosaic),

and finely crystalline in others, with the main microlites being plagioclase.

One fragment at least 1cm long is very different from the others, having a vesicular,

formerly glassy groundmass in which relatively abundant olivine euhedra (to 1mm)

have been replaced by chlorite or pale serpentine and quartz, with the characteristic

dark crystal outlines defined by very fine-grained Fe-oxide dust released during olivine

breakdown and pushed to grain boundaries. A few phenocrysts with typical augite

crystal shapes are replaced by epidote and quartz, and plagioclase microphenocrysts

are totally replaced by very fine-grained, almost isotropic aggregates of epidote,

pumpellite and chlorite.

Meandering meshworks of pale yellow to pale brown epidote traverse the rock, and

in hand specimen can be seen to follow the margins of some fragments, and pervade

the rock in other places. Similarly, patches of very low birefringent chlorite and

mosaic-textured quartz occur throughout the rock, particularly at fragment margins.

This style of alteration is typical of low-grade degradation of brecciated lava flows

(Smith 1968), the hot metamorphic fluids being channeled along fragment (and flow)

Dear Graham,

Subject: 10 Samples for Pb Isotope Analysis and Interpretation

Herewith are 10 samples from the Beulah area south of Devonport inTasmania. They come from haematite and manganese altered "Beulah"basalt thought to be part of the Mount Read Volcanics, and from rocks.attwo nearby barite occurrences. Sample locations, descriptions and leadlevels are appended. Analyses for other elements available are alsoappended.

The area contains Devonian granites and there is unequivocal Devonianskarn mineralisation associated with related granites nearby. I expecttherefore that some of these samples may have Devonian mineralisationsignatures. What we hope for is evidence of Cambrian volcanogenicmineralisation as well.

High Pb Beulah Basalt

Typically this is a massive unaltered green lava or lava breccia~

Metamorphic minerals include epidote prehnite and pumpellyite. (Lowgrade green-schist-prehnite pumpellyite facies).

The samples I have sent you are atypical in that they are altered withspecular haematite, manganese and other iron oxides and they containanomalous lead levels.

Other basalts in the district altered to mica and iron oxide, containanomalous zinc (750 ppm Zn) but no lead (60 ppm Pb).

Beulah Barite Occurrence

This occurs in a greywacke (Gog Range Greywacke). There is apossibility that the greywacke may be intercalated with the Beulahbasalts below.

Raematite is a co~~on associate of the occurrence (271705s). Lenticularmassive barite surrounded by gossan (271701) occurs at one locality. Ahighly micaceous sa~ple (271708a) close to a barite lens has also beenincluded. Massive barite does not contain visible galena yet contains2.68% Pb (271086).

This occurs parallel to the cleavage in an (intrusive?) green rhyolite.Samples of the rhyolite host and of associated haematite-quartz gossauhave been included. The barite itself contained low Pb levels «50ppm).

SUMMAEcr

The Pb isotopic composition of relatively high-Pb samples

from the Beulah Basalt, and the nearby Beulah and Paradise

Barites have been analysed and compared with signatures for

Cambrian massive sulfides as well as with minor mineralization

associated with Devonian, or older thermal events.

The Beulah Basalt has an isotopic composition consistent

with derivation from Cambrian hydrothermal fluids similar to

those responsible for the formation of the massive sulfide

deposits of the region. The Beulah Barite, and" Paradise Barite,

however have different isotopic compositions compared to the

Cambrian signature and are considered to have probably formed

during a hydrothermal event(s) unrelated to the major Cambrian

mineralizing event.

1. AIMS OF STUDY84.

The aim of this study has been to assess whether the high-Pb

Beulah basalt and the Beulah and Paradise barite occurrences are

likely to be associated with Cambrian or Devonian metallogenic

3. TARGET

All major Cambrian ore deposits of Western Tasmania (Mt

Lyell, Rosebery, Hercules, Que River, Hellyer) have essentially

identical Pb isotopic compositions indicating they were probably

formed as part of a major metallogenic event. The homogeneous

isotopic composition over the region suggests the hydrothermal,,-

systems were very large, leaching Pb and other elements from a

significant volume of crust thus averaging out local variations

in the isotopic compositions of source rocks. The Cambrian

massive sulfide isotopic signature is represented in this study

by the overlapping fields for Rosebery, Que River and Hellyer

(Figs 1 and 2) .

Minor mineralization in western Tasmania commonly consists

of discontinuous pods or veins. The isotopic composition of such

mineralization varies between occurrences, indicating the

hydrothermal systems were much smaller. Most examples of this

mineralization have isotopic compositions more radiogenic than

the Cambrian target (i.e. higher 206pb /204pb , 207pb /204pb and

208pb /204pb ratios) and some can be associated with Devonian

plutonism (e.g. Queen Hill, Mt Farrell, Figs 1 and 2» .

85.However, other examples have isotopic compositions

intermediate between Precambrian and Cambrian signatures (Figs 1.

and 2). In some, the low 206pb/204pb ratios probably result from

leaching of Pb from nearby Precambrian source rocks (e. g.

WOW/CAB, old Comstaff prospect in Oonah Formation between Ramsay

and Coldstream Rivers; Prover 3, Geopeko prospect Mackintosh East

area). The occurrence of both populations in some examples

(Marionoak, WOW/CAB) indicates the effects of different local

source rock compositions or overprinting by at least two separate

mi.neralization episodes. Although it is likely that Devonian

thermal events were responsible for the generation of these

relatively localized hydrothermal systems, it is possible they

developed at other times, even during the Cambrian.

Irrespective of the age it is unlikely that such

mi.neralization would have economic potential.

4. METHODS .~

The whole-rock samples were digested in a 7N nitric + 7N

hydrochloric solution prior to ion exchange and electroplating as

above. The samples were analysed on an ISOMASS 54E solid source

thermal ionization mass spectrometer in ful.l.y automated mode.

Precision estLmates representing 2 standard deviations about the

mean of over 700 analyses of standards are shown in the top l.eft

hand corner of the figures presented below.

5. RESULTS

The results are presented in Table 1 and in Figures 3 - 6.

Samples of high-Pb Beu~ah Basa~t plot within or adjacent to the

Rosebery massive sulfide field (Figs 5 and 6). The Beu~ah Barite

contains significantly less radiogenic Pb: 271712, 271708b and

271701 plotting as a tight group flanked by 271708b and 271705a

86.(Figs 5 and 6). The two Paradise Barite samples contain highly

radiogenic Pb and plot well to the right of the Cambrian fields

(Figs 3 and 4) .

6. DISCUSSION

The isotopic homogeneity of the Beulah Basalt samples and

the close similarity of the results to the Rosebery signature

indicate that Pb enrichment was probably associated with the same

mineralizing event responsible for the massive sulfides in the Mt

Read Volcanics. The slightly lower 206pb/204pb and 207pb/204pb

ratios compared with the Cambrian signature are consistent with

derivation from rocks with a slightly larger mantle component.

This may simply reflect region variations in the nature of the

source rocks through which hydrothermal solutions circulated

(i. e. more primitive mafic rocks), or may indicate minor

tectonic environment differences.

.-The five Beulah Barite samples have pb contents varying from

ll5ppm to 2.7%. The range in isotopic compositions is not simply

related to the Pb content; the sample with lowest Pb (27l705a, pt

8, Figs 5 and 6) contains the least radiogenic Pb. However, the

206pb/204pb ratio of the relatively low-Pb micaceous greywacke

adjacent to the barite (27l708a, pt 5, Figs 5 and 6) has probably

increased since the formation of the rock due to in situ decay of

U to Pb. Thus sample points 4, 6-8 probably indicate the true

initial isotopic composition of the barite. The ratios are

similar to those for the Voyager 2 prospect and the minor vein

mineralization discussed in section 3. Whether they represent

Devonian or Cambrian events, there is only a low probability they

are associated with a major hydrothermal system.

. 87.The Paradise Barite samples contain highly radiogenic Pb,

probably as a result of radiogenic addition of Pb since.

formation. Thus it is not possible to estimate accurately their

initial ratios. However the relatively high-Pb content of

especially sample 271762 (pt 9, Figs 3 and 4) suggests either the

samples contain elevated levels of U (20-25ppm) or the initial

ratio was close to that of Queen Hill (Figs 1 and 2).
