Placer deposits

Stannopalladinite was originally described from a locality thought to be in the Noril'sk region, and since described from the Taimyr mine, Talnakh area, of that region in western Siberia; the species was later redefined from Monchegorsk, Kola Peninsula; also at the Ugol'nri Ruch' placer, all in the USSR (HOM).

Localities

At the type locality, Ugol'nyi Ruchei Mine, Noril'sk Cu-Ni deposit, Norilsk-Talnakh Mining Region, Taimyr Peninsula, Taymyrskiy Autonomous Okrug, Krasnoyarsk Krai, Russia, stannopalladinite occurs as spherical and ovoid-shaped grains up to 0.08 mm in size, closely intergrown with tetraferroplatinum as part of flattened, prismatic crystals up to 6 mm long. Associated minerals include tetraferroplatinum and zvyagintsevite (Mindat).

At Monchegorsk, Murmansk Oblast, Russia, stannopalladinite is associated with niggliite, hessite and tellurides of platinum and palladium (HOM).
