Austinite

Austinite has only been recorded from the one locality, and is relatively common there. It occurs as transparent to opaque prismatic crystals that are yellow or sometimes greenish in colour. They occur with other zinc-bearing minerals such as adamite and willemite, or with hedyphane and quartz.
