Tsumeb is the Type Locality
Extremely rare. Third oxidation zone.
- 3rd Oxidation Zone
Paragenetic and General Notes
Erikapohlite was discovered on 44 Level, where it occurs as 0.7mm-wide seams of very thin, deep blue, lamellar microcrystals in granular quartz. It is an oxidation product of tennantite.
Erikapohlite is the calcium-dominant analogue of keyite. Small zones in erikapohlite are Mg- or Cu-dominant, representing new species that have yet to be characterised. The type specimen was purchased by Georg Gebhard in Tsumeb, in 1994. The type assemblage includes quartz, lammerite, conichalcite, and an unknown amorphous, brownish, transparent Zn,Fe,Cu (Mg,Ca) arsenate.
