Kabwe (Broken Hill)

Central Province, Kabwe, Zambia

OtherZn-Pb-V

Type
Dolomite-hosted Zn-Pb with sulfide and non-sulfide ore

Sulfide and non-sulfide bodies in Katanga Supergroup dolomites, mineralised before the last Lufilian phase. Several generations of probably hydrothermal willemite, followed by supergene smithsonite, cerussite and hemimorphite. Indicative coordinates.
