| 摘 要： | 高家堡子银矿床为辽东地区近年来发现的一大型独立银矿床，它赋存于早元古代辽河群大石桥组大理岩地层之中，受层间破碎带构造控制。矿区发育含银-铅-锌碎裂大理岩型及硅化石英脉型两种主要类型矿石。流体包裹体研究表明，前者石英中主要发育气液两相、含CO2三相、CO2及单液相四种类型的原生流体包裹体，成矿流体属H2O-CO2-NaCl体系类型，与造山型矿床成矿流体相似；后者石英中主要发育气液两相及单液相包裹体，成矿流体属H2O-NaCl体系类型，其低温低盐度特点及氢、氧同位素数据表明成矿流体主要来自大气降水。综合分析表明，本区银的大规模富集成矿作用是印支期以来以大气降水来源为主的热液活动的产物。

| Abstract: | The Gaojiapuzi silver deposit is a large silver-dominated deposit that has been discovered in eastern Liaoning Province in recent years.It occurs in marble strata of the Dashiqiao Formation,Liaohe Group of Early Proterozoic Era and is contolled by interbedded brecciation fractures.There are two kinds of ores developed in the mining district,which are silver-lead-zinc-bearing brecciated marble type and silicified quartz vein type respectively.Systematic study on fluid inclusions reveals that there are four t... |
