摘要:

康家湾金银多金属矿床是水口山铅锌多金属矿田的重要代表性矿床,以金银矿化富集为突出特点。以矿相显微镜和电子探针研究为主要手段,探讨金银赋存状态及其与成矿演化的关系。研究表明,在该矿床经历的毒砂—黄铁矿—石英、金银铅锌硫化物和石英—方解石3个成矿阶段的热液成矿作用演化过程中,Au、Ag富集于金银铅锌硫化物阶段,金银除以类质同像进入黄铁矿和方铅矿晶格之外,金主要形成Au-Ag系列独立矿物,少量为Au-Ag-Te系列矿物,银除少量构成Au-Ag系列和Au-Ag-Te系列矿物之外,主要形成Ag-Cu-Zn-Fe-Sb-As-S系列矿物,此外还有Ag-Sb-S系列和Ag-Cu-Sb-As-S系列矿物。

Abstract:

As a representative of Shuikoushan lead-zinc polymetallic orefield,Au-Ag polymetallic deposit in Kangjiawan is characterized by Au-Ag ores concentrated.Analysis of how Au and Ag are reserved and how they are related to evolution of mineralization is conducted,by using petrographic microscope and EMPA.Three mineralization processes are figured out,which are,formed by hydrothermal solution,Arsenopyrite-pyrite-quartz stage,zinc-lead sulfide stage,and quartz-calcite,respectively.Concentration of Au and Ag occurred at the zinc-lead sulfide stage.Au exist independently as a form of Au-Ag ores,except some of which enter the crystal lattices of iron pyrite and galenite by isomorphism and few of which exist in the form of Au-Ag-Te ores.Ag mainly exists in the form of Ag-Cu-Zn-Fe-Sb-As-S ores,in addition there are Ag-Sb-S series and Ag-Cu-Sb-As-S series of minerals.

Key words:  mineralization enrichment of Au and Ag, metallogenic evolution, EPMA, mineralography, Kangjiawan polymetallic deposit, Hunan Province
