热液过程贵金属的共生分离机制

依据国外贵金属最新水热实验研究和溶解度计算结果，对热液条件下金、银和铂族元素的共生分离机制进行了综述，指出源岩特征、热液性质和活动历史、配合物类型及其热动力学性质、贵金属相对溶解度和沉淀物理化学条件等因素值得予以重视。

MECHANISMS OF PARAGENESIS AND SEPARATION FOR NOBL B METALS IN HYDROTHERMAL PROCESSES

On the basis of recent hydfothermal experiments and solubility calculation of noble metals, the mechanisms of paragenesis and separation noble metals are studied. It in concluded that the characteristics of siource regions,the nature and active history of hydrothermal solution,the types and thermodynamic nature of complexes,the relative contents of noble metals,and the physicochemical conditions of precipitaticn should be emphasized.
