内蒙古阿木伊勒特铅锌矿床是2005年内蒙古自治区地质调查院承担的1︰50000矿产地质调查时发现的,属于朝不楞—梨子沟多金属成矿带的西延部分。该区化探异常元素组合主要为 Ag、Cu、Cd、Mo、Zn、Pb、As、Sd 及铁族元素,经1︰5万与1︰1万土壤测量成果对比,异常重现性好、强度增高,浓集中心明显,与地表矿化蚀变带吻合较好。但常规物探激电面积测量未发现极化体的存在,为探测深部隐伏矿体,结合地质特征,布置 CR 法剖面,取得了较好的效果。总结该矿床的地质特征、物化探特征,提出其成矿规律,为本地区下一步找矿工作的开展提供借鉴。

Amuyilete Pb-Zn deposit of Inner Mongolia belongs to the west extension of Chaobuleng-Lizigou polymetallic metallogenic belt, which was found in 2005 when 1:50 000 mineral geological survey was undertaken by Geological Survey Institute of Inner Mongolia. The geochemical anomalous element assemblage is mainly com-posed of Ag, Cu, Cd, Mo, Zn, Pb, As, Sd and iron group elements. The comparison between the 1:50 000 and the 1:10 000 soil surveys shows that the reproducibility of anomaly is very well with the increased strength and the clear concentration center. It is in good agreement with the surface mineralization alteration zones. However, there is no polarizable body existed via the conventional geophysical induced polarization area survey. To detect deep con-cealed deposits, CR profiles have been arranged combined with the geological characteristics and achieve a great result. In summary, it is to provide references of carrying out further prospecting work in this area that we shall summarize the geological, geophysical and geochemical features in the deposit and the metallogenic regularity.
