Leiteite

Leiteite is a very rare zinc arsenite. It occurs as monoclinic, colorless to pale brown, transparent crystals in parallel growth, and more commonly as cleavable masses in the deeper "germanite ores" at the type and only locality: Tsumeb mine, Tsumeb, Otjikoto Region, Namibia. It is associated with chalcocite, tennantite, reinerite, schneiderhohnite, zincian stottite, zincroselite, tsumcorite, stranskiite, and smithsonite. Leiteite is named for Luis Antonio Bravo Teixeira-Leite of Pretoria, South Africa, who first discovered the mineral.
