Merenskyite

Summary

Merenskyite is a rare telluride / bismuthinide mineral with the chemical formula (Pd,Pt)(Te,Bi)2.[3][4] It is an opaque white to light gray metallic mineral that occurs as inclusions within other minerals such as chalcopyrite. It crystallizes in the trigonal crystal system.[3]
