Formula: Pd15(Sb7-xSnx) (3≤x≤4)
Alloy of palladium, antimony
and tin, platinum group mineral
Crystal System: Monoclinic
Specific gravity: 11.22 calculated
Environments
Sluzhenikinite is a new mineral, approved in 2021 and to date (March 2023) reported only from the type
locality.
Localities
At the type locality, the Oktyabrsky mine, Talnakh Cu-Ni Deposit, Noril'sk, Putoran Plateau, Taimyr Peninsula,
Taymyrskiy Autonomous Okrug, Krasnoyarsk Krai, Russia, sluzhenikinite was discovered in the
pegmatoidal
galena–chalcopyrite massive
ore. It forms euhedral elongate lamellar crystals (100–150 μm long and 10–50 μm wide) associated with a
gold-silver alloy,
insizwaite and
myrmekitic intergrowths of
platinum-palladium minerals
such as stibiopalladinite,
maslovite and sobolevskite,
in close association with sperrylite and base-metal sulphides such as
galena, chalcopyrite,
cubanite and pentlandite
(MM 86.4.577-585).
