通过黔西南微细浸染型金矿区内独立矿床空间分布 ,同一矿床中元素在水平及垂直方向富集关系 ,成矿元素矿化富集阶段性 ,元素的相关及因子分析的综合研究 ,进一步证实了微细浸染型金矿床中金与砷、锑、汞存在既共生又分异的双重地球化学特征 .金、锑矿物的溶解度及络合物分配热力学计算表明 ,金在热液中主要以Au(HS) -2 迁移 ,而锑则主要以Sb(OH) 03 为主 ,锑在成矿晚阶段低温酸性环境中HSb2 S-4 作用有所加强 .物理化学条件变化是导致金、锑共生分异的重要因素之一 .共存于同一成矿热液中的金、锑由于其络合物类型、溶解度相异 ,及其对物理化学条件的变化作出的响应不同 ,使其沉淀在时间、空间和沉淀物种上有所差异 .
Through the spatial distribution of the independent deposits within the fine disseminated gold deposit in the southwestern Guizhou Province, the enrichment of horizontal and vertical elements in the same deposit, the stage of mineralization and enrichment of the ore-forming elements, the correlation of elements and the factor analysis, it is further confirmed In the finely disseminated gold deposit, gold and arsenic, antimony and mercury have dual geochemical characteristics of symbiosis and differentiation.The solubility of gold and antimony minerals and the thermodynamic calculation of the distribution of complex show that the gold mainly consists of Au ( HS) -2, while antimony is mainly composed of Sb (OH) 03, and antimony plays an increasingly important role in the late-stage low-temperature acidic environment of HSb2-S-4.The change of physicochemical conditions leads to the symbiosis of gold and antimony Is one of the important factors that coexist in the same mineralization hydrothermal gold and antimony due to their complex type and solubility of different, and its changes in the physical and chemical conditions to make different response to precipitation in time and space and Sediment species vary.
