Nickelaustinite

Named for the nickel-dominant chemical composition and its relationship to austinite. Nickelaustinite finds its type locality in the Bou Azzer district of Morocco and additionally has a couple newer localities in Greece and Germany. This rare mineral occurs on dolomite and is associated with roselite, calcite, chalcopyrite, and skutterudite.

Nickelaustinite from Ait Ahmane, Bou Azzer dist., Morocco

This confirmed occurence was first noted by Favreau et al (MR 38-5) as coming from vein 52 of Aït Ahmane. Though Cesbron noted its occurence at Bou Azzer, the group could not specifically identify the exact place within the complex. This is a confirmed Nickelaustinite.
