Environments
Moncheite occurs typically in small amounts in
platinum-palladium bearing massive
copper-nickel sulphide deposits. Associated
minerals include merenskyite, melonite,
sobolevskite, michenerite,
kotulskite, froodite,
sperrylite, cooperite,
laurite, braggite,
insizwaite, gold,
pyrrhotite, pentlandite,
chalcopyrite and pyrite
(HOM).
Localities
The type locality, the Monchegorsk Cu-Ni Deposit, Monchegorsk, Murmansk Oblast, Russia, is a
platinum-bearing massive
copper-nickel sulphide deposit.
Moncheite occurs in chalcopyrite as grains mostly hundredths of
a millimetre in size
(AM 48.1181).
