本文基于氢氧同位素的地球化学研究,论述了安徽月山矿田两类铜、金矿床成矿流体的来源、演化及成矿流体输运和化学反应和成矿作用动力学过程。结论认为,月山矿田金属矿床成矿流体为具复杂演化历史的岩浆水或多成因水的混合,主要成矿阶段成矿热液均以岩浆水占绝对优势,两类矿床是同源岩浆热液系统在不同的地质、地球化学环境下演化的产物,是成矿流体的等温输运反应及温度梯度输运反应等综合作用的结果。
Based on the geochemical study of hydrogen and oxygen isotopes, the authors discuss the origin and evolution of ore-forming fluids and the metallogenic fluid transport, chemical reaction and metallogenesis dynamics of two types of copper and gold deposits in the Yueshan ore field, Anhui Province. The conclusion is that the metallogenic fluid of the Yueshan ore field metallogenic fluid is a mixture of magmatic water or multi-origin water with complex evolution history. The mineralization hydrothermal fluids are dominated by magmatic water in the main metallogenic stages, Hydrothermal system in different geological and geochemical environment evolution product is the result of isothermal transport reaction and temperature gradient transport reaction of the ore-forming fluid.
