中文摘要:
      通过矿床地质特征及成岩、成矿因素研究,认为海西晚期发生挤压造山产生NE向褶皱,沿褶皱轴海西晚期似斑状中细粒花岗闪长岩、石英闪长岩侵入,在与西别河组片岩的接触带内侧,形成接触破碎蚀变岩型—裂隙充填型的热液铜多金属矿床,矿区内蚀变矿化多赋存在北东向构造内。围岩蚀变较为发育,与成矿关系密切的为硅化、黄铁矿化、碳酸盐化、萤石化等。文章在以往地质成果的基础上,通过成矿地质背景、矿区地质概况和矿床地质特征的阐述,着重对成矿控制因素、矿床成因及找矿标志进行分析,认为该区具有较好的成矿地质条件和找矿前景。
英文摘要:
      Through the geological features of ore deposit and study on geochronology of mineralization, the paper thinks polymetallic deposit is high temperature hydrothermal type deposit,which formed by contact metasomatic between acidic magmatic hydrothermal in Yanshan period and wall-rock.The main structure line is in the northeast, and distribution of ore deposits are controlled by deep fault belt, the mining area in the altered mineralized occurs in the northeast construction.Mineralization and alteration of the study area is developed,related to the ore-forming silicification, greisenization, hornfels, Pyrite mineralization carbonation, fluorite mineralization etc.On the basis of the previous geological results, this paper analyzes the genesis of ore deposit, ore material source and metallogenic regularity by elaborated on the metallogenic geological background, geological survey of mining area and geological characteristics of the deposit, thinks the area has good geological conditions and prospecting foreground.
