altaite
Definition
A rare metallic mineral, a lead telluride with the chemical formula PbTe, crystallizing in the cubic (isometric) system; it stands out structurally due to a yellowish-white or tin-white color with bright yellow reflections, high density, and perfect cleavage. It was initially discovered in the Altai Mountains, from which it derives its name, encountered in hydrothermal veins often associated with native gold and other tellurides.
