Tsumeb is the Type Locality
Very rare. Second oxidation zone.
- 2nd Oxidation Zone
The type specimen is from 30 Level. Subsequent discoveries were made in the 1960s, 70s, and 80s on 29, 30, and 31 Levels, essentially the middle portion of the second oxidation zone.
Paragenetic and General Notes
Stottite occurs as pseudo-octahedral crystals and anhedral masses in germanium-rich sulphide ores. Exceptional crystals to 20 mm are known. Associated minerals are zincian siderite, quartz, ludlockite, leiteite, and schneiderhöhnite.
Cesbron et al. (1977) has suggested that reinerite is also
part of the same paragenesis. The close association of stottite with
three, and perhaps four, zinc arsenites suggests that it forms under
somewhat reducing conditions (Southwood, 2015).
Stottite is readily confused with siderite, wulfenite, stolzite, or even scheelite.
