| 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。

| Abstract: | 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 alt... |
