ETYM German, from blenden to blind, dazzle, deceive, from blind blind. So called either in allusion to its dazzling luster; or (Dana) because, though often resembling galena, it yields no lead. Related to Sphalerite.
1. A mineral, called also sphalerite, and by miners mock lead, false galena, and black-jack. It is a zinc sulphide, but often contains some iron. Its color is usually yellow, brown, or black, and its luster resinous.
2. A general term for some minerals, chiefly metallic sulphides which have a somewhat brilliant but nonmetallic luster.
Zinc sulfide; name of several lustrous metallic sulfides.
Mineral composed of zinc sulfide with a small proportion of iron, formula (Zn,Fe)S. It is the chief ore of zinc. Sphalerite is brown with a nonmetallic luster unless an appreciable amount of iron is present (up to 26% by weight). Sphalerite usually occurs in ore veins in limestones, where it is often associated with galena. It crystallizes in the cubic system but does not normally form perfect cubes.
