Very rare. Second (?) and third oxidation zones.
- 2nd Oxidation Zone
- 3rd Oxidation Zone
The so-called "Zinc Pocket" on 44 Level, in the third oxidation zone.
Paragenetic and General Notes
Köttigite was first observed at Tsumeb by Bartelke (1976) who described radiating clusters of needle-like crystals (to 2 mm) associated with "dark-green adamite" (presumably cuprian adamite or zincolivenite). This material was probably from the second oxidation zone.
In the third oxidation zone, köttigite occurred in the so-called "Zinc Pocket", on 44 Level, from which Gebhard (1999) described blue balls of köttigite associated with leiteite and white adamite.
