摘要
基于包裹体类型、均一温度、压力、盐和氢氧同位素研究，认为成矿流体主要来源于岩浆，但有天水混合。综合研究包裹体特征，成矿物化条件，微量元素特征和围岩蚀变组合、矿石矿物组合以及金的地球化学性质，提出本区金主要以Ａｕ－Ｓ，Ａｕ－Ａｓ和Ａｕ－Ｃｌ形式迁移，构造活动造成的热液系统压力的骤降是金沉淀的主要因素。
Studies on the types, salinity, homogenization temperature, pressure, composition of theinclusion and hydro-oxygen isotope from Bankuan gold deposit indicated that the metallogenic fluid mainly derived from magma,partly from native water. It was proposed that goldhas mainly been transported in the form of complexes of Au-S of An-As, Au-Cl secondly, andthe abruptly decreasing of the pressure in the hydrothermal system derived from structuralactivities were the principal factor of causing gold precipitation,based on synthetic studies onmetallogenic physicochendcal conditions, wall rock alteration, trace element, mineral assemblage,inclusion,and geochemistry of gold.
