Tsumeb is the Type Locality
Extremely rare. Second (?) and third oxidation zones.
- 2nd Oxidation Zone
- 3rd Oxidation Zone
Paragenetic and General Notes
Feinglosite is the zinc analogue of arsenbrackebuschite.
The type material (feinglosite) was collected during the 1970s. The level in the mine on which it was found is not known, but it is almost certainly from the second oxidation zone. The type assemblage comprises feinglosite on massive chalcocite, w. wulfenite, anglesite and goethite.
Two additional finds of feinglosite have been made:
(1) Feinglosite has been found in association with anglesite, cerussite, wulfenite, and residual galena on material originally in the collection of John Innes, Tsumeb mineralogist in the the late 1970s and early 1980s (Mark Feinglos, personal communication to M.Southwood, 2012).
(2) Feinglosite has been found in the third oxidation zone in association with gypsum (Gebhard, 1999).
