摘　　要：本文将银山成矿体系作为富含H_2S、CO_2的NaCl体系,对Cu、Pb、Zn、Ag和Au等金属元素在该体系降温过程中的地球化学行为和银山矿床的成矿过程进行了计算机数字模拟,并与沸腾降温体系进行对比,证明了成矿体系地球化学演化对金属元素的迁移与沉淀具有重要影响,成矿流体地球化学摸拟在矿床成因、深部成矿预测和区域成矿规律研究中具有重要意义。A H2S-and CO2-rich NaCl solution system was selected as the analogue of Yinshan ore fluids and the geochemical behaviors of Cu, pb, Zn, Ag and Au in the process of temperature lowering in the system and the ore-forming processes of the Yinshan deposit were simulated and the process with digital computer. Compared with that in the boiling system. It suggests the influence of ore fluid geochemical evolution on the migration/deposition of metals and the significance of ore fluid geochemical modelling in studies of ore genesis, ore prospecting in depth and regional metallogeny.
