What is Bowieite?
Bowieite is a rhodium-iridium-platinum sulfide mineral (Rh,Ir,Pt)2S3, found in platinum-alloy nuggets from Goodnews Bay, Alaska. It was named (by the IMA in 1984) after the British scientist Stanley Bowie (1917–2008), in recognition of his work on identification of opaque minerals. The mineral crystallizes in the orthorhombic crystal system (space group Pbcn).
