| 摘 要： | 内蒙古巴彦哈尔金矿床位于华北陆块北缘艾力庙-锡林浩特中间地块西北缘.矿床赋存于中元古代温都尔庙群的绢云石英片岩和绿泥石片岩中.矿床的形成与区内韧性剪切带及华力西期岩浆活动关系密切.矿区内共圈定出5个矿体，总体走向为北西向，矿体呈似层状或透镜状产出，矿石类型包括石英脉型和糜棱蚀变岩型.金矿化与硅化和黄铁绢英岩化蚀变关系密切.结合矿床的矿体地质、矿物成分、矿物嵌布及围岩蚀变特征以及前人包裹体测温结果，认为矿床类型为浅成低温热液型金矿.

| Abstract: | The Bayanhar gold deposit of Inner Mongolia is located in the northwest margin of Ailimiao-Xilinhot median mass in the northern margin of North China Plate. It is hosted in the sericite-quartz schist and chlorite schist of Wenduermiao Group, Mesoproterozoic. The formation of the deposit has a close relationship with Variscan magmatic activity and ductile shear zone in the region. Five orebodies are delineated, which are occurred as stratiform or lentiform and generally in NW direction, with ore types of quartz vein and mylonite altered rocks. The gold mineralization is closely related to silicification and beresitization. According to its geological characteristics, mineral composition, dissemination, wall rock alteration features and the former measurement of fluid inclusion temperature, it is concluded that the Bayanhar gold deposit genetically belongs to epithermal type. |
