Vasilite Osmium Cooperite Vysotskite
Comments: BSE image taken with a SEM of the sulfide-dominant microparagenesis filling a gas vacuole. Cooperite crystal surrounded by Pd-Cu-Pt-S phase (vasilite?), vysotskite and osmium laths (white) in chalcopyrite-bornite matrix (dark). (CanMin 38:1258).
Location: Pustaya River placer deposit, situated within the Koryak-Kamchatka platinum-bearing belt of Alaskan-type intrusions in eastern Russia.
Scale: See Image.
