通过对典型金矿成矿动力学研究 ,探讨了成矿元素活化、迁移、富集的规律 ,认为 :( 1 )早期的韧性剪切活动使断裂带处于高应力、高能量区 ,原有的物质平衡被破坏 ,成矿物质重新分配 ,Au、 Ag等成矿元素并没有在此发生富集 ,反而发生贫化 ;( 2 )晚期的韧脆性—脆性活动使断裂带处于一个相对低应力、低能量的开放环境 ,Au、Ag等成矿元素随成矿流体从围岩或深部运移到断裂带 ,并在此富集成矿。
Through the study on the metallogenic dynamics of typical gold deposits, the rules of activation, migration and enrichment of ore-forming elements are discussed. The results show that: (1) Early ductile shear activities make the fault zone in high stress and high energy area, The material balance is destroyed and the ore-forming materials are redistributed, and the ore-forming elements such as Au and Ag are not enriched here, but rather depleted. (2) The ductile-brittle-brittle activities in the late period make the fault zone at a relatively low stress, Low-energy open environment, Au, Ag and other metallogenic elements with ore-forming fluid migration from the surrounding rock or deep to the fault zone, and in this rich mineralization.
