Formula: Pd4Cu3Zn
Alloy of palladium, copper and
zinc, platinum group mineral
Specific gravity: 11.16 calculated
Hardness: 4½ to 5
Colour: Steel-white
Environments
Bortnikovite is a relatively new mineral, approved in 2006.
Localities
At the type locality, the Konder alkaline-ultrabasic massif, Ayan-Maya district, Khabarovsk Krai, Russia,
bortnikovite occurs as steel-white, metallic overgrowth rims of approximately 50–150 μm on larger
isoferroplatinum grains. The deposit is a unique
placer deposit derived from a concentrically zoned alkaline
ultramafic massif, and dunite
is the primary source of the platinum group minerals themselves.
Associated minerals include
titanite, perovskite,
magnetite, isoferroplatinum,
chlorite and bornite
