Tectonic Environment of Hydrothermal Gold Deposits and Physico_chemistry of Ore_forming Fluid
热液金矿床控矿断裂性质与成矿流体的物理化学

Metallogenic physico_chemical conditions of hydrothermal gold deposits are greatly associated with ore_controlling fault environment .A comparison of physico_chemical parameters of fluid inclusions from different tectonic environments(including Xiaoqinling,Jiaojia,Linglong and Taibei gold deposits)has been studied .The result shows that the pressures of ore_forming fluids of gold deposits in ductile shear zones are higher,so the values of CO 2/H 2O of fluid inclusions are high.K +/Na + and F -/Cl - of fluid inclusions varies in different tectonic environments,which is not only related to chemistry of host rocks,but also related to tectonic stress.Because ore_forming fluid pressures vary,other parameters of physico_chemistry change sysmaticly,very useful for gold prospecting.
