| 摘 要： | 小南沟银铅锌多金属矿为辽宁省葫芦岛地区一新探明的矿床。文章对该矿床的矿石样品进行了光薄片鉴定、电子探针分析、包裹体测试、同位素测试等研究工作。研究表明,矿床的有用元素为银,共(伴)生铅、锌;银与方铅矿、黄铜矿、黝铜矿密切相关,主要以类质同象形式赋存于方铅矿、黄铜矿、黝铜矿内,少量以自然银形式包裹在方铅矿内。成矿可分成2期(热液成矿期、表生成矿期)4个阶段(早期黄铁矿-绢云母、石英阶段;石英-银、多金属硫化物阶段;碳酸盐化阶段;表生氧化阶段)。矿床成因为受构造控制的中低温热液矿床。

| Abstract: | Xiaonangou Ag-Pb-Zn deposit is newly discovered in Huludao island area,Liaoning province.This paper presents results of identification of polished sections,electronic probe analysis,measurements of fluid inclusion and isotopic analysis of ore from the deposit.Ag is the main ore element and Pb,Zn byproduct.The former is associated with galena,chalcopyrite,tetrahedrite occurring as isomorphs and a little as native silver inclusion in galena.The ore-forming process is divided into two periods and four stages,i.e.the primary hydrothermal period and supergene period and the primary stages of pyrite-sericite,Quartz-Ag-multi-metal sulfides and carbonation and the secondary supergene stage.Genetically,it is a structure-controlled epi-meso-thermal deposit formed in long term and multi-stages. |
