摘　　要：以ETM图像数据为信息源,波谱理论为基础,采用基于单波段图像分类的生成彩色合成图像法,突出和增强了与金矿成矿有关的矿源层、围岩蚀变、控矿构造和热液蚀变带等遥感影像标志特征。提取了新疆哈图地区内生金矿的矿化蚀变信息,圈定了综合遥感矿化蚀变信息异常,并对圈定的异常在哈图地区进行了遥感找矿应用,经野外实地验证,发现了托玛尔勒和喀尔色巴依克斯套两处金矿蚀变带,取得了良好的找矿效果。Based on ETM image information sources and wave spectrum theory, with the support of the color composite images on the basis of mono-wave band category, remote sensing image signs related to gold ore-forming such as source bed, wall rock alteration, ore-controlling structures and thermal alteration zones have been intensified. Remote senses of ore-finding have been conducted in the alienated anomaly areas in Hatu, Xinjiang by extraction of ore-forming alteration and comprehensive remote sensing mineralization alteration information of endogenetic gold deposits. A good ore-prospecting resuh is obtained, which is attest by field works, and Tuomaerle and Kaersebayikesi goht alteration belts are found.
