云南普朗铜矿三维地质建模与深部找矿预测

Three-dimensional geological modeling and deep prospecting prediction of the Pulang copper deposit in Yunnan Province

云南普朗铜矿位于滇西北迪庆藏族自治州东部,已查明矿床铜金属量达大型规模,并具有超大型的远景。通过对普朗铜矿成矿地质背景的分析及基础地质资料的搜集,利用三维可视化建模技术构建普朗铜矿的三维地质模型,确定有利控矿要素并构建找矿预测模型。将证据权法与信息量法相结合进行综合成矿预测,最终圈定找矿靶区2处,为普朗铜矿的下一步找矿勘查工作提供参考。

Pulang copper deposit is located in the east of Diqing Tibetan Autonomous Prefecture in northwest Yunnan.It has been found that the copper amount of the deposit has reached a large scale and has a super large prospect.Through the analysis of the geological background of the Pulang copper deposit and the collection of basic geological data,the three-dimensional visualization modeling technology was used to build the three-dimensional geological model of the Pulang copper mine,determine the favorable ore-controlling elements and build the prospecting prediction model.Through the comprehensive metallogenic prediction of a combination of the weight of evidence method and information method,two prospecting target areas were delineated,which provides reference for next prospecting of the Pulang copper deposit.
