摘要
Cu-Zn alloy minerals were revealed with Examination of ores from the Jinshan gold deposit, Xinjiang Autonomous Region, China, by using optical microscope and EPMA. Compared with Zn-Cu alloy minerals discovered previously, those Zn-Cu minerals were in α portion, which has Cu content of over 80% in Zn-Cu alloy phase diagram. Those rare alloys were formed in a strongly reducing environment with absent oxygen and low sulfur activities. Combined with the study of mineralization stages of the Jinshan gold deposit, those alloy minerals were considered forming in Stage IV of the epithermal mineralization epoch.
