Sulphides ( Сульфиды )

 This is a large and complex group of minerals in which bonding is both ionic and covalent in character. The sulfide group has the general formula AMXP, where X, the larger atom, is typically S but can be As, Sb, Te, Bi, or Se, and A is one or more metals. The sulfo-salts, which are much rarer than sulfides, have the general formula AMBNXP, where A is commonly Ag, Cu, or Pb, B is commonly As, Sb, or Bi, and X is S. The sulfide and sulfo-salt minerals are generally opaque, heavy and have a metallic to sub-metallic lustre.
