Aggregate on matrix of Zincolivenite crystals with very well-defined faces and edges, translucent, bright, and with a deep and uniform color. A high-quality specimen of Zincolivenite, a species approved in 2006, for which precise analyses are required to be sure that it really corresponds to that species. It is accompanied by small yellow crystals of Gartrellite, a species that has also been analyzed.
Tsumeb Mine is one of the world’s most renowned mineral localities. Geologically, it represents a polymetallic replacement deposit hosted by Proterozoic dolostones of the Otavi Group, formed by the interaction of metal-rich hydrothermal fluids with carbonate rocks. This setting produced an exceptionally complex orebody, celebrated for its remarkable mineralogical diversity, particularly secondary minerals of copper, lead, zinc, arsenic, and germanium, with many species first described from this classic locality.
Tsumeb Mine, Tsumeb, Otjikoto Region Namibia (08/1980)
Specimen size: 4.1 × 2 × 1.3 cm = 1.61” × 0.79” × 0.51”
