摘　　要：为了使用遥感手段在莽西地区快速圈定找矿预测区,该文以KOMPSAT-2、ETM遥感影像为基础,采用目视解译与人机交互判读相结合,对莽西地区的线性、环形构造进行了解译,并采用ASTER数据通过主成分分析法提取了遥感蚀变异常信息,系统地分析了线-环构造及异常信息与成矿的关系,同时结合已知矿床(点)资料,圈定了4处成矿有利预测区,为研究区内下一步地质找矿工作提供了参考依据。Based on KOMPSAT-2 and ETM remote sensing data,and by using visual interpretation and human computer interaction,this paper interpreted the linear and circular structures in west Mangling pluton, and extracted the alteration anomaly information by principal component analysis while using ASTER data. The relationship between the linear-circular structure and alteration anomaly information was systematically analyzed; Combined with the known mineral deposits, 4 favorable metallogenic prognosis areas were given,which could provide reference for future ore poroslaecting work in this area.
