Alphabetical List Tree DiagramDetailed Mineral List:
| β Baryte Formula: BaSO4 |
| β Calcite Formula: CaCO3 |
| β Cerussite Formula: PbCO3 Habit: Small prismatic crystals and small clusters, the later almost always twinned. Colour: Usually chalky dull white on surface from weathering, translucent grey-white interior. Description: Likely more prevalent and better specimens in active mining days. Collecting on the small remaining dumps yielding obvious but not impressive specimens. |
| β Chalcocite Formula: Cu2S |
| β Chalcopyrite Formula: CuFeS2 |
| β 'Chert var. Novaculite' ? Description: The cited reference gives a question mark after the term "novaculite". See my messageboard discussion for May 20, 2019. The rock is highly improbable to be sedimentary, hence a variety of chert - a strictly sedimentary rock term - does not fit. Rather the abundant material being referred to is almost certain to be rhyolite. The largely uniform light grey color reduces the amount of interest in it as a lapidary material, but it can and has been used for that. |
| β 'Chlorite Group' |
| β Covellite Formula: CuS |
| β 'Freibergite Subgroup' Formula: (Ag6,[Ag6]4+)(Cu4 C2+2)Sb4S12S0-1 |
| β Galena Formula: PbS |
| β Gold Formula: Au |
| β Malachite Formula: Cu2(CO3)(OH)2 |
| β Muscovite Formula: KAl2(AlSi3O10)(OH)2 |
| β Muscovite var. Sericite Formula: KAl2(AlSi3O10)(OH)2 |
| β 'Psilomelane' |
| β Pyrite Formula: FeS2 |
| βͺ Pyromorphite Formula: Pb5(PO4)3Cl Habit: Highly diverse. Includes tabular with basal pinacoids all the way to slender prismatic with complete pyramid faces. Some of the later had yellow equant second-generation crystals attached epitaxially to the long colorless prism - "corn on the cob"! Also "spindles", "barrels", "rice grains", and acicular spheroids. Colour: Every color reported for the species. Shades of green of course, also water-clear colorless, beige, tan, yellow, orange, white. But of special interest is the unique carnation pink crystals. Unfortunately these appear to be due to F-centers or lattice voids and not a chromophore. So they quickly fade in the sunlight. Description: See details under habits and colors. This is a much smaller mine than the nearby Silver Hill Mine. But this mine surpasses Silver Hill in the amazing diversity of colors and habits of the pyromorphite. |
