Phase relations and mineral assemblages in the copper-lead-sulfur system

Abstract

The phase relations of the Cu-Pb-S system were investigated in evacuated silica tubes at temperatures between 200 and 1130 degrees C. A sulfide liquid, which may be important in ore genesis, remains stable to 508 degrees . Above 523 degrees , this liquid prevents the coexistence of galena and copper sulfides. The addition of iron and zinc to the system does not stabilize the liquid below the minimum melting temperature in the Cu-Pb-S system. H (sub 2) O does not measurably effect the melting relations. Phases investigated include galena, chalcocite, digenite, covellite, djurleite, lead, copper, and a new ternary phase.
