Localities
The type locality, the Kombat Mine, Kombat, Otavi Constituency, Otjozondjupa Region, Namibia, is a
copper - lead -
silver deposit. Kombatite occurs as bright yellow anhedral grains,
0.2 mm across, with a light yellow streak, adamantine lustre and perfect cleavage
(AM 73.928).
Associated minerals include hematite,
calcite, hausmannite,
kentrolite and a mineral similar to
harkerite
(HOM).
At the Wesley Mine, Westbury on Trym, Bristol, England, UK, little is known about the original workings. It is recorded
that there was active mining for manganese,
iron and lead in the Bristol area in the
17th to 19th Centuries, but the era and purpose of the Wesley Mine remain unknown. The single kombatite specimen
consists largely of calcite adhering to a small amount of
manganese oxide. The kombatite is found as a single bright orange
grain, about 2 mm in length, embedded within the calcite. It is irregular in
shape and has a pronounced cleavage causing the grain to fracture into discrete layers
(JRS 11.51-53)
