Formula: PtBiTe
Telluride, cobaltite group, platinum- and bismuth- mineral. Maslovite originally was assigned to the ullmannite subgroup, but further studies indicate that it probably belongs to the pyrite subgroup (AM 74.1171).

Environments

Igneous environments
Hydrothermal environments

Maslovite occurs in galena-rich portions of massive cubanite-chalcopyrite and mooihoekite ores. Associated minerals include altaite, sobolevskite, moncheite, michenerite, hessite, froodite, paolovite, tatyanaite, sperrylite, atokiterustenburgite, galena, chalcopyrite, cubanite and mooihoekite (HOM).

Localities

At the type locality, the Oktyabrsky mine, Talnakh Cu-Ni Deposit, Noril'sk, Putoran Plateau, Taimyr Peninsula, Taymyrskiy Autonomous Okrug, Krasnoyarsk Krai, Russia, maslovite occurs in galena-rich portions of massive cubanite-chalcopyrite and mooihoekite ores or host rocks near the contact. The maslovite occurs as elongated, sometimes rounded grains with maximum dimensions 100-120 microns in diameter. It is usually present in the centre of complex polymineralic intergrowths of altaite, tellurium-bearing sobolevskite, moncheite, michenerite, platinum-bearing michenerite, hessite, froodite and sperrylite (AM 65.406-407).
