Formula: Rh2S3
Sulphide of rhodium
Specific gravity: 6.93 calculated
Hardness: 7
Colour: Pale grey to Pale grey-brown
Environments
Bowieite occurs in platinum alloy nuggets in placer deposits. Common
associates include iridium, laurite,
osmium and platinum
(Mindat).
Localities
At the Gaositai Cr-PGE deposit, Gaositai, Chengde County, Chengde, Hebei, China, bowieite occurs in
platinum-bearing ultramafic rocks
intruded into a granite and
hornblende
gneiss complex
(HOM).
At the type locality, the Salmon River-Red Mountain District, Goodnews Bay, Bethel Census Area, Alaska, USA, bowieite
was found as anhedral grains, to 0.5 mm included in other platinum group minerals
in a placer platinum deposit. Associated minerals include
platinum-iridium,
platinum, osmium,
laurite and silicate inclusions. In addition an unidentified,
anhedral grey phase was found as abundant inclusions 0.02 to 0.5 mm in size. Preliminary analysis indicated that this
phase contains major rhodium, iridium and
sulphur, with minor platinum
(CM 22.543-552).
