Geologic s t u d i e s i n t h e Ketchikan area

The western ha l f of t h e Ketchikan quadrangle i s under la in by a

broad b e l t o f r eg iona l ly metamorphosed Paleozoic and Mesozoic sedi-

mentary and volcanic rocks which grade f r m gxeenschis t t o amphibolite

f a c i e s . These rocks a r e in t ruded by numerous g r a n i t i c s tocks of Cre-

taceous t o Miocene age. Gran i t i c and amphibolite-grade r eg iona l ly meta-

morphosed rocks of t he Coast Range metamorphic-plutonic c m p l e x occur

throughout t h e e a s t e r n and northern po r t ions of t h e quadrangle.

The e a r l i e s t comprehensive d iscuss ions of the geology of t h e

Ketchikan area a r e contained i n r e p o r t s by Wright and Wright (1908)

quadrangles has been completed and a geologic map a t a sca le of

1:250,000 has been published (Berg and o thers , 1978).

Sampling

Standard procedures were followed i n co l l ec t ion , preparat ion, and

ana lys i s of rock geochemical samples. The samples are primarily grab

samples chosen t o provide data on background values fo r a lithologic

u n i t . The majoxity of these samples a r e representa t ive of the domi-

nant l i tho log ies a t the sample s i t e . A l e s s e r number of samples were

col lec ted from minor l i tho log ies , known mineralized occurrences, o r

outcrops that a r e conspicuously iron-stained o r contain v i s i b l e metal-

l i c minerals.

Sample preparat ion and ana ly t i ca l procedures

Samples were crushed, a s p l i t was pulverized and a s p l i t of t h i s

material analyzed. Analyses were performed by the Branch of Exploration

Research of the U . S . Geological Survey for up to 30 elements by the six-

s t e p semiquantitative emission spectrographic method (Grimes and

Marranzino, 1968), and f o r gold, copper, lead and zinc by atomic

absorption spectrophotmetry (Ward and o the r s , 1969) - Samples col lec ted in

1972 and 1973 were analyzed f o r mercury by a flameless atomic absorption

mercury-vapor detection technique (Vaughn and McCarthy, 1964). Some

analyses were not performed on a l l samples. The semiquanti tat ive

spectrographic analyses w e r e performed by J. E, Abrams, E. F. CooZey,

K. J. Curry, G. W. Day, C. L. Forn, R. T. Hopkins, R. C. KarLson,

J. W. McNamera, and D. F. Siems. The atomic absorption analyses

were done by R. B. Carten, J, A. Criswell , D. E. Detra, J. D. Hoffman,

R. W. Leinz, A. L. Meier, R. L. Miller, D. G. Muxrey, R. M. O'Leary,

J. A . Roybal, R. F. Sanzolone, A. J. Toevs, and W. W. Vaughn.

Geochemical data

Locations of rock sample sites a r e iden t i f i ed by s t a t i o n numbers

on plate 1. The a n a l y t i c a l data f o r the samples a re 'g iven i n t a b l e 6

and a r e iden t i f i ed by station number w i t h a letter appended t o the

s t a t i o n number t o d i s t ingu i sh d i f f e r e n t samples from the same station.

Some samples were re-analyzed a s part of a t e s t of ana ly t i ca l variance.

These sample numbers appear twice i n t a b l e 6 along with da ta f o r both

analyses.

Each sample has been assigned a rock type and is labeled i n

t a b l e 6 with a rock name code consis t ing of a tm-letter rock-name

symbol which may be followed by one o r more two-letter mineral-mdifier

symbols. An explanation of these rock-name and mineral-nwdifier codes

is l i s t e d i n t a b l e 4 (p. 17).

Analy t ica l Values

Analy t ica l r e s u l t s a r e repor ted a s percent of t h e sample ( f o r

spectrographic ana lyses o f Fe, M g , Ca, and T i ) and as parts pe r mi l l i on

the u n i t s used f o r each a n a l y s i s are l i s t e d i n table 1 (p. 6).

P rec i s ion

Tests have been performed t o determine t h e a n a l y t i c a l p rec i s ion

of the s ix-s tep semiquant i ta t ive spectrographic technique used by t h e

Branch of Explorat ion Research (Motooka and Grimes, 1976). These t e s t s

i n d i c a t e that the frequency with which values from repeated analyses

of the same sample w i l l f a l l within t h e c l a s s interval containing the

"true" value ( a s measured by t h e mean of a s e r i e s of a n a l y t i c a l r u n s ) ,

p lus o r minus one and two adjoining i n t e r v a l s is approximately 83 per-

c e n t and 96 percent, respectively. For example, i f a value k s reported

as 3.0, the p r o w i l i t y is -83 t h a t a repeated analys is w u l d be re-

ported as 2.0, 3.0, or 5.0. T h i s study found a n a l y t i c a l variance to

be consistent f o r a variety of geologic materials and t o show no

appreciable d i f ference between elements or concent ra t ion ranges ex-

cep t near the l i m i t s of determinabil i ty. Another experiment (Johnson

and o t h i r s , 19771 suggests that ana ly t i ca l pxecision v a r i e s appre-

c iably between elements. Analyses by the atomic absorption m e t b d s

are not reported on the six-step sca le ; they a r e more sens i t ive and

more p rec i se than spectrographic analyses.

S t a t i s t i c a l summary

The ana ly t i ca l da ta were processed by a computer program known

as GEOSUM and the program's output is presented i n t a b l e 5. For sam-

ples which have been re-analyzed, the values l i s t e d second i n the data

t a b l e have been arbitrarily omitted from t h e s t a t i s t i c a l summary t o re-

duce bias . The GEOSUM program i s designed t o summarize and tabula te

geochemical data--primarily from semiquanti tat ive spectrographic analy-

ses. A l l d i s t r i b u t i o n s a re t r ea ted i n terms of the six-step class

i n t e r v a l s described above and thus the atomic absorption data are

regrouped to fit into these i n t e rva l s . The program output consists

of: (a) a frequency d i s t r i b u t i o n table , histogram, summary of quali-

fied values, range of values and geometric mean and deviat ion f o r each

element, and (b) a s t a t i s t i c a l summary for all elements, which includes

geometric means and geometric deviat ions.

The histograms are on a logari thmic s c a l e and a r e computed using

the c l a s s i n t e r v a l s of t h e .s ix-s tep semiquant i ta t ive s ca l e . The h i s to -

gram b a r s a r e canposed of X ' s ; each X r ep re sen t s approximately 1 per-

cent of the t o t a l number of samples analyzed f o r t h a t element. Decimal

numbers are p r i n t e d by the computer as powers of 10 , f o r example:

-1 ' 7.0e-01 means 7 . 0 ~ 1 0 o r 0.7

7.0ei00 means 7 . 0 x 1 0 ° o r 7.0

7.0e+01 means 7.0 x 10 or 70.0

7.0e+02 means 7 . 0 ~ 1 0 2

The frequency d i s t r i b u t i o n t a b l e s , histograms, and s t a t i s t i c s f o r

each element =re derived us ing on ly data values wi th in the range of

a n a l y t i c a l de te rmina t ion which have been used s i n c e 1975. Between

1968 and 1975, t h e lower l i m i t s of de t e rminab i l i t y were r a i s e d f o r

t i s t i c s a r e biased and t h e histograms incomplete.

The sumnary a t t h e end of table 5 shows which elements have qua l i -

fied values , as w e l l a s t h e number of va lues having each type o f quali-

f i c a t i o n . The summary a l s o p r e s e n t s a recomputed geometric and geo-

me t r i c dev i a t i on using a method devised by A. J. Cohen f o r t r e a t i n g

and on t h e page wi th in t h e t a b l e f o r t he p a r t i c u l a r element. For ele-

ments with q u a l i f i e d d a t a , t h e es t imates of mean and geometric devia-

t i o n are unbiased i n a s t r i c t sense only where the data are derived

from a log-normal parent population, but experiments have shown t h a t

Large departures from t h i s requirement do not usually inva l ida te the

r e s u l t s . Acceptance and use of t h e est imates, however, are the

r e spons ib i l i ty of the user .

The geometric mean is the anti logari thm of t h e ar i thmet ic mean

of the logarithms of the analyses. It is not a n est imate of geochem-

i c a l abundance bu t of "cent ra l tendency" (or c h a r a c t e r i s t i c value)

for a frequency d i s t r i b u t i o n that is approximately symmetrical on a

logarithmic sca le . The geometric mean i s use fu l f o r characterizing

many geochemical d i s t r ibu t ions . The geometric devia t ion i s the ant i log-

ar i thm of the standard deviat ion of the logarithms of the analyses.

For fu r the r discussion of geometric mean and geometric deviat ion

and of Cohen's method f o r censored d i s t r i b u t i o n s , see ~ i e s c h (1963,

1967) . B i a s and v a r i a b i l i t y a f fec t ing i n t e r p r e t a t i o n

In reviewing t h e data i n t a b l e 6 and the s t a t i s t i c a l summary i n

t a b l e 5 , severa l sources of bias and v a r i a b i l i t y i n the data must be

considered. Factors including time l imi ta t ions , weather, snow and

vege t a t i ve cover, outcrop exposure, and a v a i l a b i l i t y of he l icopter

landing s i t e s prevented uniform sampling i n all areas. Uneven sample

dens i ty a l s o resul ted from more concentrated sampling of some areas

which show evidence of mineral izat ion such as i ron-staining o r v i s i -

ble meta l l i c minerals. This p rac t i ce has biased the data s l i g h t l y i n

favor of samples containing values above t r u e background l eve l s . The

requirement of t r u l y random sampling--that a l l p o t e n t i a l samples have

an equal likelihood of being selected--is not-met. I n addi t ion , the

rock samples were col lec ted from a l a rge a r e a , where l i t h o l o g i c units

of various o r i g i n s or rock types may comprise several d i s s imi la r geo-

chemical populations. N o attempt has been made here to group samples

on the bas i s of geological o r geochemical a f f i n i t y . The summary of

the values thus provides only a general indica t ion of the trends t h a t

may be present .

Var iab i l i ty of any value i s influenced by many f a c t o r s , including

the d i f f i c u l t y of obtaining representa t ive samples o f inhomogeneous

media, va r i a t ion i n sample preparat ion, and v a r i a b i l i t y inherent i n

the ana ly t i ca l techniques. It is likely with any l a rge data-set t h a t

e r r o r s have occurred i n recording, key-punching and ed i t ing t h e data

which have gone undetected. Therefore, high values f o r a s ing le ele-

ment o r a s ing le s i t e should be considered questionable ind ica to r s o f

bedrock mineral izat ion.
