Chalcocite (uncommon locale) Trimingham Coll.

Item Description

Chalcocite specimens are rare from this less well-known New Mexico locale. Intergrown, sharp to subhedral, matte-finish, metallic-gray chalcocite crystals to about 7 mm cover the ore vein of massive chalcocite, microcrystalline pyrite, green copper oxides, and other sulfides on this rich old ore specimen. Not particularly fine to look at, but it is a rare and rich crystallized ore specimen for the locale. Ex Bob Trimingham Collection. Formerly in the Pappy Yeats Collection of the Texas Tech Geology Department (A well known collection of a prominent geologist, sold off in the 1980s. The piece probably dates to prior to 1950). A must for the locality or species collector.
