| 中文摘要: |
| 帮浦铅锌矿是西藏自治区墨竹工卡境内规模较大的一处矿山,经过多年开采目前已处于资源枯竭期,急需开展深、边部找矿。本文介绍了矿区地质成矿基本信息,利用双频激电法对矿区进行勘查,根据总结的成矿模型结合其它相关地质资料,分析了成矿地质要素与视电阻率及视幅频率异常之间的关系,针对区内视幅频率异常干扰较为严重,提出利用小波分析手段对视幅频率进行分解和重构,对重构后的视幅频率异常,根据其与成矿地质要素的密切程度,筛选出区内可能与成矿相关的视幅频率异常,通过钻探验证取得了预期找矿效果。 |
| 英文摘要: |
| Bangpu Lead-Zinc Mine is one of the largest mines in Mozhu Gongka of Tibet Autonomous Region.After years of mining,the mine is depleted of resources.depth and margin area prospecting is very urgent.The authors introduce the basic information of Geology and mineralization in mining area,and investigate working-place using double frequency induced ptolarization method.We analysis the relationship between geological factors and IP anomaly on the basis of known metallogenic model.Due to the serious interference of apparent amplitude frequency,we decompose and reconstruct it by wavelet analysis.At last we screened out the apparent frequency anomaly which are closely related to mineralization considering geologic feature and the result of wavelet analysis,and get the desired perception of geological prospecting.Ore-prospecting results have been achieved by drilling. |
