#argyrite

• Argyrite — An archaic or literary mineralogical designation historically used as a synonym for argentite or silver sulfide (Ag2S), or for other silver-rich ores. In a structural and historical sense, the term represents a transitional form borrowed from Western European and Hellenic scientific terminology (based on the root argyros - silver), encountered in old geology treatises and mining catalogs before the standardization of modern international nomenclature.
• Argyrites — A historical, archaic, or bookish term used in old mineralogy and archaeology to denote a type of rock, mineral, or lead oxide (litharge) that exhibits a silvery luster or contains fine silver inclusions.
