Tsumeb is the Type Locality
Very rare. Second oxidation zone.
- 2nd Oxidation Zone
Pinch and Wilson (1977) record that crystals up to c. 8 mm were found, from "the 900 and 1100 m levels" (= 30 Level and 36 Level).
Paragenetic and General Notes
Söhngeite occurs in aggregates of twinned crystals, in which the individuals present with a characteristic perpendicular orientation. Very rarely söhngeite occurs without this twinning; a single specimen is known with untwinned pseudo-cubic crystals (Gebhard, 1999).
On the type specimen söhngeite occurs in tiny cavities in germanite / gallite rich sulphide ore.
