Chalcocite - Wikipedia Chalcocite ( ˈkælkəˌsaɪt ), [6][7] copper (I) sulfide (Cu 2 S), is an important copper ore mineral It is opaque and dark gray to black, with a metallic luster
Chalcocite: Mineral information, data and localities. Chalcocite easily converts to djurleite under the electron beam through the rearrangement of Cu atoms (Pósfai and Buseck, 1994) Small amounts of the Cu2S phase may deposit from supersaturated volcanic gas, as shown in an experiment (Africano et al , 2002; 300-700oC deposition range for this particular experiment) Compare UM2003-43-S:CuFePdPt
