Monchetundraite, Pd2NiTe2, a new mineral from the Monchetundra layered intrusion, Kola Peninsula, Russia

Monchetundraite, Pd2NiTe2 is a new mineral discovered in the the Monchetundra layered intrusion, Kola Peninsula, Russia. It forms euhedral grains (up to about 20 μm) intergrown with kotulskite and pentlandite. Monchetundraite is brittle and has a metallic lustre. In plane-polarized light, monchetundraite is white to creamy pinkish white, strongly pleochroic and strongly anisotropic on prismatic sections with rotations tints of pale blue, orange...
