Tsumeb is the Type Locality
Extremely rare. The level from which the type specimen was recovered is unknown.
- 2nd Oxidation Zone
Paragenetic and General Notes
Prosperite occurs as radiating groups of slender, white to colourless crystals to 10 mm in length, and 1 mm in diameter.
On the type specimen prosperite occurs in vugs in oxidising chalcocite ore. Two types of vugs were observed.
In the first, the prosperite is associated with druses of bright green conichalcite and pale blue-green rosettes of adamite crystals.
In the second type, the vugs are lined with dull, pale-green druses of cuprian austinite, and also contain adamite and prosperite.
The chalcocite in the matrix contains minute blebs of silver-amalgam, and cuprite was also identified on the matrix. Several then-unknown new minerals were also noted (Gait et al., 1979). Subsequently, Keller and Bartelke (1982), listed these additional species as koritnigite, gaitite, and o'danielite - all new minerals described from Tsumeb between 1978 and 1979.
