Formula:
Pb2Cu(PO4)(SO4)(OH)
Colour:
Emerald-green sometimes bluish green; green in transmitted light.
Lustre:
Adamantine, Sub-Adamantine, Vitreous, Sub-Vitreous, Resinous, Waxy
Hardness:
Specific Gravity:

Crystal System:
Monoclinic
Name:
Named in 1912 by Karl Heinrich Emil Georg Busz for the town of the type locality - Tsumeb, Southwest Africa (now 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.
