摘要
内蒙古莫力达瓦旗葛根台-小黑山地区位于大兴安岭中北段东乌旗-嫩江Cu-Mo-Pb-Zn-W-Sn-Cr成矿带.通过对研究区与区域典型矿床成矿地质背景及控矿条件的对比分析,认为葛根台-小黑山地区具有热液型金铜钼矿、剪切带型金矿和斑岩型铜钼矿床的成矿潜力.采用对控矿有利条件信息要素的提取和要素赋值的统计方法,尝试对研究区进行金铜钼等找矿靶区预测工作,为后续区域地质调查及找矿工作提供参考.
Gegentai-Xiaoheishan area in Molidawa Qi of Inner Mongolia is located in the East Ujimqin Qi-Nenjiang Cu-Mo-Pb-Zn-W-Sn-Cr metallogenic belt in the northern-central Daxinganling Mountains.Based on the comparative analysis of metallogenic geological setting of regional typical deposits in the study area and ore-controlling conditions,it is concluded that Gegentai-Xiaoheishan area has the metallogenic potential of hydrothermal Au-Cu-Mo deposits,shear zone-type Au deposits and porphyry Cu-Mo deposits.Through the statistical method of information element extraction of favorable ore-controlling conditions and factor assignment,the prospecting target areas for gold,copper and molybdenum deposits in the area are predicted,which provides reference for the regional geological survey and prospecting in the future.
