摘　　要：本文通过对玛沁原始磁异常特征、数据处理异常特征,结合物性及地质资料进行分析,工作区经历了数次地球动力学条件的改变,构造、岩浆活动及沉积作用期次多,且复杂,形成了良好的成矿地质条件,找矿前景十分乐观。以期对该地区寻找类似矿床提供参考依据和帮助。Through the analysis of the characteristics of magma original magnetic anomaly, abnormal data processing, physical properties and geological data, the working area has undergone several changes of the geodynamic conditions, and the tectonic, magmatic and sedimentary periods are more and more complicated, forming a good metallogenic geological condition, and the prospect of prospecting is very good. Optimism. In order to provide reference and assistance for finding similar deposits in this area.
