摘要
采用了矿区地球化学异常、主量元素、稀土元素和微量元素地球化学研究手段和分析方法,阐述了金等成矿元素的富集规律及物质来源。宝兴沟矿区处在规模大、强度高的水系、土壤及岩石异常内,都具有Au、Ag、As、Sb、Pb中低温热液型金矿的元素组合特征。与成矿关系密切的闪长岩脉、闪长玢岩脉、花岗细晶岩脉具有高钾钙碱性玄武岩石特征,岩浆具幔源特征。矿床成矿物质主要来源于侏罗系二十二站组砂岩以及燕山晚期闪长岩脉和闪长玢岩脉,脉岩为成矿提供了热源和动力。
this article states the enriched regulars of metallogenetic elements and material sources by adopting Geochemical research and analytical methods of orefield geochemical anomaly,major elements,rare earth and trace elements.Baoxinggou mining is in the prolific drainage system and intense soil and rock anomaly,with the integrated characteristics of epithermal mining elements as Au,Ag,As,Sb,Pb.Diorite dyke,diorite porphyry vein and Fine-grained granite dykes that are closely related with mineralization possess the characteristics of Kcalc-alkaline basalt stone and mantle-derived magma.Deposit-forming materials are mainly from the sandstone in Jurassic twenty-two Station and Yanshanian diorite dyke and diorite porphyry dyke.Dikes provide heat and power for oreforming.
