Vote for your favorite mineral in #MinCup26! - Sphalerite vs. Anorthite
Both zinc ore Sphalerite and calcium plagioclase feldspar Anorthite have perfect cleavage that will split cleanly if you hit them with a hammer, but only one can claim a larger split of your votes!

A Pb-Ag-F-V-Mo-Cu group of claims within the larger group of Adams 20 claims. Located in the SW¼ sec. 31, T.4S., R.18W. (protracted). Owned by Adams, Stephans, Hudson.

Mineralization is irregular and spotty masses of coarsely crystalline galena, usually coated with anglesite, cerussite and lead oxides, in a gangue of crystalline fluorite and brown to black calcite with iron-stained gouge and brecciated wall rock, in lensing fault zones up to 8 feet wide, cutting Mesozoic shale, metamorphosed to slate. Intrusions of diorite-porphyry dikes and a few small irregular masses of quartz porphyry. Vanadinite and wulfenite are found locally in vugs in the mineralized zones and some minor oxidized copper minerals.
