Austinite

specimen number:
2057145

location:
Ojuela Mine, Mapimi, Durango, Mexico

description:
Austinite is a rare calcium zinc arsenate mineral that typically forms in the oxidized zones of zinc and lead deposits where arsenic bearing minerals have weathered. It was first described in 1915 from the Gold Hill mining district in Utah and was named in honor of Austin F. Rogers, an American mineralogist. Austinite usually occurs as small pale yellow to colorless crystals, often forming radiating sprays or thin crusts on matrix rock. It is commonly associated with other secondary arsenate minerals such as adamite and olivenite, and is sought by collectors for its delicate crystal groups and rarity. This example shows attractive sparkling green crystals across the top of matrix. In good condition. A good example for the species.
