Tsumeb is the Type Locality
Extremely rare. Second and third oxidation zones.
- 2nd Oxidation Zone
- 3rd Oxidation Zone
The type specimen is from "the 1000 m level" (= 31 Level) in the second oxidation zone (Strunz, 1960), and comprises pinkish crystals of chudobaite with cuprian adamite, olivenite, and conichalcite. In the third oxidation zone (44 Level ?) chudobaite occurs as colourless-white material in the cores of zoned cuprian adamite crystals (Gebhard, 1999) and as colourless crystals on ferrilotharmeyerite accompanying cuprian adamite. Chudobaite has also been found as colourless crystals embedded in chalcocite (Gebhard, op.cit.).
Paragenetic and General Notes
The type specimen, with rose-coloured, equant crystals to 5mm is now considered to be atypical (Gebhard, 1999). Colourless crystals to 1mm, and the presence of chudobaite in the cores of cuprian adamite crystals are the more common modes of occurrence.
