Localities

The type locality is Borehole 1818, Monchetundra deposit, Monche tundra intrusion, Murmansk Oblast, Russia. Palladothallite is a new mineral (approved in 2020) found here. It occurs in orthopyroxenite with disseminated nickel-copper-iron sulphides and in near-surface oxidised ore of an orthopyroxenite unit. In the holotype specimen, the new mineral forms anhedral grains about 1 to 20 μm in size intergrown with bortnikovite. Palladothallite and bortnikovite form a rim around tulameenite, platinum-palladium-iron-copper alloys, and platinum-palladium-iron-copper “oxides” in a goethite matrix CM 59.1821-1832
