Localities
At the type locality, the Komsomol'skii mine, Talnakh Cu-Ni Deposit, Noril'sk, Putoran Plateau, Taimyr Peninsula,
Taymyrskiy Autonomous Okrug, Krasnoyarsk Krai, Russia, kravtsovite occurs as equant inclusions (ranging in
size from a few μm to 40–50 μm) in silicates and pyrite, commonly intergrown
with vysotskite and a
gold-silver alloy, in aggregates
(100–200 μm across). Other associated minerals include telargpalite,
cooperite, braggite,
sopcheite, stibiopalladinite,
sobolevskite, moncheite,
kotulskite, malyshevite,
insizwaite, chalcopyrite,
diopside, grossular and
chlorite
(EJM 29.597-602).
The deposit consists of vein-disseminated hydrothermal mineralisation in
skarn rocks beneath a basaltic
sill
(HOM).
