中文摘要:
      昌图锡力位于大兴安岭中南段锡林浩特-霍林郭勒多金属成矿带上,周边已发现花敖包特、扎木钦等大型铅锌银矿床,区域上具有较大找矿潜力。以1:5万区域地质调查工作为基础,通过在内蒙古昌图锡力地区开展1:5万和1:1万土壤测量,确定了异常的范围,缩小了找矿靶区,通过异常的元素组合特征确定找矿的主攻矿种为锰银铅锌矿;利用激电中梯测量、激电测深等物探方法进一步圈定出矿体空间分布位置与形态,为勘探工程布设提供了直接依据;在物化探综合异常套合较好及地表矿化发育地段,开展钻探工程验证,勘探到了锰银铅锌矿体,取得了较好的找矿效果。综合运用物化探方法在该区找矿是可行、有效的,对区域上的矿产勘查工作具有指导意义。
英文摘要:
      Changtuxili of Inner Mongolia lies in the Xilinhaote - Holingol polymetallic metallogenic belt, south-middle section of the Da Hinggan Mountains,around which the Huaaobaote and Zhamuqin large-size Ag- Pb- Zn polymetal deposits have been found,implying a great potential of further prospecting in this area. Based on regional geological survey of 1:5 million, the abnormal range and prospecting target area are defined by soil geochemical survey at scales 1:50000 and 1:10000. Element association of the anomalies shows that the prospecting should be focused on Mn-Ag-Pb-Zn ores. Location and shape of ore bodies are delineated by IP ladder measurement and IP sounding, providing a evidence for layout of exploration projects. Drilling at the sites with geophysical and geochemical anomalies reveal existence of the Mn-Ag-Pb-Zn ore. This practice demonstrates that the integrated geophysical and geochemical methods are feasible and effective in searching for ore deposits and has guiding significance for mineral exploration in the region.
