| Abstract: | By measuring section about structure and altered rocks in the Xincheng gold deposit,combining structural observation and geochemical analysis,the authors obtained that structure and geochemistry have synchronous variation characteristics:(1) altered rock zonation along the Jiaojia fault is fault gouge-silicified zone-beresitization zone-highly potassic granite-weakly potassic granite-unaltered granite;(2) gold mineralization mainly exists in the silicified zone and beresitization zone;(3) fault gouge-myloni... |
