Very rare. Second and third oxidation zones.
- 2nd Oxidation Zone
- 3rd Oxidation Zone
Paragenetic and General Notes
The type specimen for stranskiite is from 30 Level, in the second oxidation zone, where stranskiite occurs on chalcocite as tabular
crystals in radiating aggregates to 10 mm, and also in massive form. The
colour is cyan-blue, and the crystals are vitreous and
In 1994, stranskiite was discovered in the third oxidation zone, on 44 Level, as 2 mm sprays of white crystals on a blue unknown (GS 3 of Gebhard; Gebhard, 1999).
Gebhard (op. cit.) suggests that the blue colour of the original stranskiite find may be atypical and that white stranskiite (as found in the third oxidation zone) may be more common.
