Member of:Brackebuschite Group
Name:
Named after the town of the type locality - Tsumeb, Namibia.


Brackebuschite Group. The phosphate analogue of Arsentsumebite.

A secondary mineral in polymetallic ore deposits. Chemically verified Tsumeb tsumebite is rare and most unanalyzed specimens so labeled are, most likely, arsentsumebite.
