内蒙古莫力达瓦旗葛根台-小黑山地区金铜钼找矿靶区预测

    PROSPECTING TARGET PREDICTION OF GOLD-COPPER-MOLYBDENUM DEPOSITS IN GEGENTAI-XIAOHEISHAN AREA OF MOLIDAWA QI, INNER MONGOLIA

    • 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.

       

      Abstract: 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.
