摘　　要：为充分发挥遥感技术在地质构造判读及矿化蚀变信息提取方面的快速优势,以若羌县戈边山地区为研究区,基于ASTER、ETM多光谱遥感及Quick Bird高分遥感数据,采用图像增强技术和比值+主成份分析方法,提取了研究区构造、隐伏(侵入)岩体及蚀变遥感异常信息。结果表明,解译构造情况与区域构造格架基本吻合,蚀变信息分布不仅与已知矿床(点)和矿化蚀变范围有很高的匹配度,且能将该区赋矿层位很好的表现出来,验证了本次研究方法的有效性,并为下一步系统构造研究和找矿工作提供依据。This study is to give full play to the fast advantages of remote sensing technology in the interpretation of geological structures and information extraction of mineralized alterations,the Ge Bian Shan in Ruo Qiang County as the study area,based on the ASTER,ETM multispectral remote sensing and Quick Bird high resolution remote sensing data,use the image enhancement technology and ratio+principal component analysis method,extracted structure,rock mass and mineralized alteration information from the study area.The results show,interpretation of the structure is basically consistent with the regional tectonic framework,mineralized alterations not only have a high degree of match with known deposits(spots)and mineralization alterations.and it can show the ore-bearing horizon of the area well,The validity of this research method is verified,and it provides the basis for the next step in system construction research and prospecting work.
