oxidized zones of lead deposits. Its color varies
from pale yellow to yellowish-brown to orange-
yellow to orange-red, brownish, greenish, white
and colorless.
Wulfenite is a secondary lead mineral often found
as thin tabular crystals with a bright orange-red,
yellow-orange, yellow or yellowish grey colour in
the oxidized zones of hydrothermal lead deposits.

The word "quartz" is derived from
the German word "Quarz" and its
Middle High German ancestor
"twarc", which probably originated in
Slavic (cf. Czech tvrdý ("hard"),
Polish twardy ("hard")). Quartz is
the most common mineral found on
the surface of the Earth. It is a
natural form of silicon dioxide.

Apophyllite was named in 1806 by Rene Just Haüy from the Greek for "away from" (ἀπό, apo)
and "leaf" (φύλλον, phyllos), in allusion to the way it exfoliates upon heating. * The name was
recently revised from apophyllite-(KF) to fluorapophyllite-(K) (Hatert et al,European Journal of
Mineralogy 25, 2013).
Stilbite is from Greek "stilbein", to glitter
of shine, or "stilbe", a mirror, alluding to its
pearly or vitreous luster.

The Azurite name was derived from the ancient Persian lazhward, meaning "blue", in allusion to the color. The name was changed to azurite in 1824 by Francois Sulpice Beudant. Malachite was named in antiquity (see Pliny the Elder, 79 CE) as “molochitus” after the Greek μαλαχή, "mallows," in allusion to the green color of the leaves. It became known in the new spelling, malachites, at least by 1661.

Epidote was named in 1801 by Rene Just Haüy
from the Greek επιδοσιζ "Epidosis" = "increase"
in allusion to the common crystal characteristic
of one longer side at the base of the prism.
Clinozoisite and Epidote are end members of a
solid solution series with epidote containing
more iron. Epidote is the Al2Fe3+ analogue of
Clinozoisite.

Azurite, Dioptase, and Malachite are secondary copper minerals frequently found in the oxidized zones of Cu-bearing ore deposits. Tsumeb is a world-famous Cu-Pb-Zn-Ag-Ge-Cd mine, renowned for a wealth of rare and unusual minerals. It was discovered and initially operated in 1907 and was closed in 1996 for economic reasons. The name origins of malachite and azurite were previously described on slide 7. Dioptase was named in 1797 by Hauy from the Greek for "through" and "to see" in allusion to the visibility of internal cleavage planes.

Galena was named by Pliny the Elder in 77-79 from the Greek "galene" meaning lead ore. It is the primary ore mineral of lead. Worked for its lead content as early as 3000 BC, it is found in ore veins with sphalerite, pyrite, chalcopyrite, tennantite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces. The crystals are bright when fresh but often tarnish after exposure to air.

Stilbite was named in 1797 by Jean Claude de la Métherie from Greek στιλβη "stilbein", to glitter of shine, or "stilbe", a mirror, alluding to its pearly or vitreous luster. Additional varietal names and synonyms have been proposed: blättricher zeolit, hypostilbite, puflerite, radiated zeolite, and syhedrite. Chemical suffixes were added by the IMA.

Sphalerite, also known as Blende or Zinc Blende, is the major ore of zinc. When pure (with little or no iron) it forms clear crystals with colors ranging from pale yellow (known as Cleiophane) to orange and red shades (known as Ruby Blende), but as iron content increases it forms dark opaque metallic xls. (known as Marmatite). Named in 1847 by Ernst Friedrich Glocker from the Greek σφαλεροζ "sphaleros" = treacherous, in allusion to the ease with which dark varieties were mistaken for galena, but yielded no lead. Originally called blende in 1546 by Georgius Acricola (Georg Bauer). Known by a variety of chemical-based names subsequent to Agricola and before Glocker including "zincum”.

Heulandite was named in 1822 by Henry James Brooke in honor of Johann Heinrich "John Henry" Heuland (1778 – 1856). Heuland is among the best known of all 19th-century British mineral dealers. Cooper (2006) wrote of him: "Heuland's influence on mineral collecting in England was enormous; his predilection for fine specimens legendary, and his determination to obtain good locality information ahead of his time."
Heulandite is a low temperature zeolite found in a wide variety of geologic environments: volcanic rocks, metamorphic rocks, pegmatites, tuffs, and deep-sea sediments.

Pyromorphite was named in 1813 from the Greek for "fire" and "form", because, after being melted into a globule, a sample will begin to take on a crystalline shape during cooling. Pyromorphite is a secondary lead mineral found in the oxidised zones of lead deposits. It typically forms as green, yellowish, brownish, greyish or white barrel-shaped hexagonal prisms, in clusters or as druses on matrix. The individual crystals are often modified or etched, giving a hopper-like appearance. This lead chloride phosphate forms a complete series with Mimetite (lead chloride arsenate), and many specimens are intermediates between the two end-members.

Calcite is an important rock forming mineral. It forms in sedimentary deposits as limestone, can be regionally or contact metamorphosed into marbles and rarely forms igneous rocks (carbonatites). It also is a common gangue mineral in hydrothermal deposits. Calcite stalactites such as the one shown here form in mines and caves due to slow deposition over time by dripping water rich in calcium carbonate. In Bisbee, AZ both the Southwest Mine and the Copper Queen Mine have produced calcite stalactites.

Quartz has been known and appreciated since pre-historic times. The most ancient name known is recorded by Theophrastus in about 300-325 BCE, κρύσταλλος or kristallos. The varietal names, rock crystal and bergcrystal, preserve the ancient usage. The root words κρύοσ signifying ice cold and στέλλειυ to contract (or solidify) suggest the ancient belief that kritallos was permanently solidified ice. Adularia is a more ordered low-temperature variety of Orthoclase. It is generally found in alpine-type parageneses. The varietal name originated in 1780 by Ermenegildo Pini based on the name of the type locality, the Adula Massif (part of the Gotthard massif), Switzerland.

Fluorite is found as a common gangue mineral in hydrothermal veins, especially those containing lead and zinc minerals. The species was named in 1797 by Carlo Antonio Galeani Napione from the Latin, fluere = "to flow" (for its use as a flux). The term fluorescence is derived from fluorite, which will often, but not always, exhibit this effect. The element fluorine also derives its name from fluorite, a major source for the element.

The mineral Calcite was named in ancient
times by Gaius Plinius Secundus (Pliny the
elder) in 79. The name is derived from
Calx, Latin for Lime. Calcite is highly
variable in color and crystal forms, but it
is most easily recognized by its reactivity
to acids, even weaker acids like vinegar.

Eurypholis boissieri is a

from Lebanon (Haqel and
Hajoula) during the Cenomanian
stage (~95 million years ago) of
the Cretaceous period.
Eurypholis was a medium sized
fish with a pointed snout, large
eyes and a big head. This big head
had very large jaws with sharp-
pointed teeth. It also goes by the
name "viper fish".

Hemimorphite is a secondary mineral found in weathered portions of zinc deposits. It was named in 1853 by Adolph Kenngott in allusion to the hemimorphic morphology of the crystals (i.e.: the two ends of a crystal are terminated by different crystal faces). Many names were assigned to this species previously including calamine.

Since the early 1800s, fluorite was mined in southeastern Illinois. The fluorspar-rich region, which reaches from southeastern Illinois into parts of Kentucky, was called the Illinois-Kentucky Fluorspar Mining District. In Illinois, fluorite was mined almost exclusively in Hardin and Pope Counties. The main production came from fissure-vein deposits in the Rosiclare district, and stratiform (bedding plane) deposits in the Cave in Rock district. Most mining was underground, as much as 1,300 feet deep, but open-pit mines operated where fluorite deposits intersected land surface. The last fluorspar mine in Illinois closed in December 1995.
