摘　　要：新巴尔虎左地区位于得尔布干成矿带西南端,现已在周边发现多个与火山岩、次火山岩有关的大型及超大型热液型矿床。但本区工作程度相对较低,本次研究在总结前人工作的基础上,对其开展1∶5万土壤地球化学测量。通过分析18种元素的土壤地球化学特征,发现本区Pb、Zn、Ag、Mo等元素具有较好的异常。本区异常多分布于成矿有利部位,具有良好的找矿潜力。综合考虑地球化学异常元素的组合及异常区成矿地质条件和地球化学条件,圈定综合异常12处,并确定4个找矿靶区,为下一步找矿工作提供了依据。The Xinbaerhuzuoqi area is located in the southwest end of the Deerbugan metallogenic belt.There are several large and super-large hydrothermal deposits which related to volcanic rocks and subvolcanic rocks in the surrounding area.The geological work here is sparsely carried out.During the study soil geochemical survey at scale 1∶50000 was completed based on the previous work.By analyzing the soil geochemical characteristics of 18 elements Pb,Zn,Ag and Mo anomlies were well delineated.The anomalies are mostly distributed in the favorable part of the mineralization thus potential for further prospecting.Considering the combination of geochemical anomaly element and geological conditions 12 soil geochemical anomalies were delineated of which 4 are chosen as prospecting targets for the coming years.
