In the main stage Cu-Pb-Zn mineralization, Cu was precipitated prior to Pb and Zn. The Cu mineralization in the mylonites is dominated by stockworks while breccia mineralization is common in Pb-Zn ores and the fragments are cemented by sphalerite, galena, and pyrrhotite (Zhong et al., 2012). Ore fabrics and mineral assemblages of Cu and Pb-Zn ...
