摘要
Based on the geochemical analyses, bismuth is closely correlated to the skarn and copper mineralization. Analysis by electron probe, bismuth mainly occurs in the bismuth minerals and bismuth-bearing sulfides. The wittichenite is the major bismuth mineral in the Jiama deposit. It occurs as two occurrences, foliated/xenomorphic granular and dropwise in bornite, chalcocite and tetrahedrite. According to the occurrences and electron probe data, the wittichenite may form in two epochs at short time interval with normal chemical component and lower Bi, higher Cu and S, respectively. Therefore, bismuth in Jiama deposit should be comprehensively utilized, and it is also a significant clue for prospecting of copper mineralization.
