摘　　要：在蚀变矿物填图这一方面,国内外均有大量的技术与研究,其精准性和快捷性也不断的通过不同技术的运用而提高。对于运用ETM和ASTER数据来进行多光谱填图的文献也有很多,但是都是单一或混合两种数据来做,没有将两者明确的做过对比。本文在分析、学习和实践的基础上,对ETM和ASTER两种光谱数据填图的效果作一对比,研究两者的异同在运用ETM数据进行矿化蚀变填图的基础上,以现代成矿理论为指导,综合ASTER数据,利用遥感技术,进行地质构造解译和矿化蚀变信息提取的工作,初步查明区域成、控矿地质条件和矿化(蚀变)类型,开展矿产资源潜力遥感评价,提供一批矿致异常和找矿线索,为后续矿产资源勘查提供一批找矿远景区和找矿靶区,解决找矿需求。For the alteration mineral mapping ,there already exists a large number of domestic and foreign technology and research .According to the use of different technologies ,its accuracy and quickness have been improved continually .There are many literatures about multi-spectral mapping through the use of ETM and ASTER data as well ,however ,all kinds of the data show only a single work or their combination without any clearly-done contrast .Based on the analysis ,study and practice ,this paper make a comparison to ETM and ASTER spectral data mapping results to study the similarities and differences between the two . As modern metallogenic theory as a guide ,by complexing ASTER data through the use of ETM data to do the mineralization and alteration mapping ,and combined with the use of remote sensing technology ,this study conducts geological interpretation and mineralized alteration information extraction ,gets a preliminary investigation of regional mineralization ,ore geology and mineralization (alteration ) type ,carries out remote sensing evaluation of mineral resource potential ,provides a number of mineralized anomalies and ore prospecting clues ,so that it can delineate a number of prospecting areas and prospecting targets for the subsequent exploration of mineral resources ,and resolve prospecting needs .
