摘　　要：磁异常区对应不同磁化率的地质体,磁异常梯度带对应岩性界线和断裂构造。根据地表出露岩性,以点带面借助磁测资料的数据处理结果,划分覆盖区下不同的地质岩性,指出重要的构造边界,达到辅助地质填图的目的,为圈定找矿靶区和断裂构造研究提供重要依据。This paper shows the application of 1：50000 high precision magnetic prospecting in the geological mapping of the Chaishhai area in Jeminay county,Xinjiang.Different magnetic anomalies correspond to different magnetic suscep- tibility geologic bodies and gradient zone corresponds to lithologic boundary and fault structure. According to outcropli- thology,we divide different lithology under overlay through data processing result of magnetic survey,pointting out the important tectonic boundaries to achieve the purpose of auxiliary geological mapping and provide an important basis for the study of prospecting target area and fracture structure.
