综合物化探勘查方法在内蒙古巴彦沟铅锌矿找矿中的应用OA
Application of integrated geophysical and geochemical exploration method in Bayangou Pb-Zn deposit of Inner Mongolia
巴彦沟地区位于大兴安岭中南段索伦镇—黄岗Fe-Sn-Cu-Pb-Zn-Ag成矿亚带,近年在其周边发现扎木钦、复兴屯等铅锌银矿床,区域找矿前景优越.在巴彦沟铅锌矿开展1∶1万地质填图和土壤测量工作,缩小找矿靶区,利用激电中梯测量、激电测深初步圈定含矿地质体的空间位置与形态.结果显示:矿体赋存于火山岩和火山碎屑岩中,受火山机构控制,具有中低阻中高极化特征.优选矿化蚀变、物化探异常套合部位开展钻探验证,共发现83条矿体,累计获得Pb+Zn推断资源量3.10× 104 t,取得较好的找矿成果.总结研究区综合物化探勘查方法可为区域找矿提供参考.
Bayangou area of Inner Mongolia is located in Suolun Town-Huanggang Fe,Sn,Cu,Pb,Zn,Ag mineralization sub zone in the central-southern part of the Greater Khingan Mountains,and Ag-Pb-Zn poly-metal deposits in Zhamuqin and Fuxingtun around this area were newly discovered,implying a great potential of further prospecting in this area.1∶10 000 geological mapping and soil survey was conducted in Bayangou Pb-Zn deposit to reduce the prospecting target.Location and shape of ore bodies were delineated by IP intermediate gra-dient survey and IP sounding.The results show that ore body occurred in volcanic rocks and clastic rocks,con-trolled by volcanos,with the characteristics of low resistance and medium-high polarization.The drilling verifi-cation was carried out at the preferred locations where mineralized alteration geophysical and geochemical anoma-lies overlap.Eighty-three ore bodies were identified and the presumed resources of Pb+Zn were to be 3.10 × 104t,indicating favorable mineral exploration results.The integrated geophysical and geochemical exploration method was summarized in the study area,which could provide references for ore prospecting.
