【摘要】 热液金矿床的成矿物理化学条件与控矿断裂构造环境有着密切联系。作者对比了不同构造环境（小秦岭、焦家、玲珑和太白金矿）流体包裹体物理化学参数特征，表明韧性剪切带环境中的金矿成矿流体压力大、ＣＯ２／Ｈ２Ｏ数值也高。不同构造环境中流体Ｋ＋／Ｎａ＋、Ｆ－／Ｃｌ－的差别不仅与容矿岩石化学特征有关，也与构造应力作用有关，同一矿田内，甚至同一断裂带内，因所处构造部位不同，成矿流体压力也不同，致使其他物理化学参数的系统变化，这对地质找矿具有实际意义。更多还原

【Abstract】 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更多还原
