摘　　要：遥感已经成熟的运用于农业、环境、矿产等各个领域,对于地质,遥感提取蚀变信息,识别岩性、构造等发挥着重要的作用,它广阔的视野和对地表物体的真实反映给地质工作带来了宏观和更加直观的参考价值。本文主要以遥感数据为基础,主成分分析方法为主,对矿产结构发育中的蚀变信息进行了蚀变提取。根据蚀变信息在野外查证中发现一处矿脉,并以此作为工作区的矿产预测区。Remote sensing has been used in various fields such as agriculture,environment and mineral resources.It plays an important role in geological and remote sensing extraction of alteration information,identification of lithology and structure,etc.Its broad field of vision and true reflection of surface objects have brought macroscopic and more intuitive reference value to geological work.In this paper,the mineral structure development is extracted by alteration mainly by remote sensing information extraction.According to the alteration information,a mineral structure vein was found in the field investigation,and it was used as the mineral prediction area of the working area.
