| 摘 要： | 英城子金矿床位于兴蒙造山带东缘，矿床产于近东西向韧性脆性剪切带（靡棱岩带）内，矿体主要呈透镜状、似层状和脉状产出.矿石矿物主要为黄铁矿、闪锌矿和黄铜矿，主要结构为交代结构、乳滴状结构、半自形-他形结构，主要构造为浸染状构造、脉状构造、条带状构造.成矿作用先后经历了4个阶段：石英-毒砂-黄铁矿阶段、石英-黄铁矿阶段、石英-多金属硫化物阶段和石英-方解石阶段.成矿流体总体属于中温、低盐度、低密度的CO2-CH4-H2O体系.英城子金矿床与国内外典型的造山型金矿相比具有诸多相似之处，其成因类型属于造山型金矿.

| Abstract: | The Yingchengzi gold deposit,located in the east margin of the Xingan-Mongolia orogenic belt,occurs in the E-W-trending of mylonite zone,with ore bodies in veins and lenticular forms.The assemblages of ore minerals are pyrite,chalcopyrite and sphalerite,with metasomatic,dropwise and subhedral-anhedral textures and disseminated,veined and banded structures.The mineralization can be divided into four stages,namely,quartz-arsenopyrite-pyrite stage,quartz-pyrite stage,quartz-polymetal sulfide stage and quartz-calcite stage.The ore-forming fluids belong to CO2-CH4-H2O type characterized by moderate temperature,low salinity and low density.The Yingchengzi gold deposit shares some common characteristics with the typical orogenic gold deposits from both China and overseas.Its genesis may be assigned to orogenic type of gold deposit. |
