Environments
Sobolevskite occurs in massive and disseminated copper -
nickel –
platinum group minerals, in
copper deposits in
organic-rich limestone, and along grain boundaries in silicates in layered intrusives
(HOM).
Localities
At the Lubin mine, Lubin–Sieroszowice mining district, Lower Silesian Voivodeship, Poland, sobolevskite is associated with
platinum-bearing gold and
palladium
(HOM).
At the type locality, the Oktyabrsky mine, Talnakh copper-nickel Deposit, Noril'sk, Putoran Plateau, Taimyr Peninsula, Taymyrskiy Autonomous Okrug,
Krasnoyarsk Krai, Russia, sobolevskite occurs as grains, usually less than 0.1 mm in size, in massive (mainly) and disseminated
mooihoekite-chalcopyrite,
troilite-pyrrhotite and
chalcopyrite-cubanite ores. lt is most frequently observed
in intergrowths with paolovite and sperrylite, and rarely with
native silver, polarite,
altaite, taimyrite,
talnakhite, chalcopyrite,
cubanite, mooihoekite,
troilite, pyrrhotite and
galena
(AM 61.1054, HOM)
