| 摘 要： | 文章以新疆西准噶尔托里金矿带为例，基于ETM数据源，在矿区矿化蚀变体系系统研究基础上，以典型岩、矿石地物波谱的差异性为依据，设计出适合本区的混合矿化蚀变信息分解-复合提取方法，通过混合蚀变信息分解、多变量蚀变信息增强、对增强图像（复合）合成3个工作环节，形成最终的蚀变信息提取图像。经对比后，有18处遥感异常为已知金矿的反映，有3处遥感异常已提供国土资源大调查使用。

| Abstract: | In this essay, the mineralization-alteration systems of Tuoli gold belt, Xinjiang, China, were studied systematically. Based on the spectrum difference of the surrounding-rocks and altered rocks and RS ETM data a new method of extracting the mixed mineralization-alteration information was designed. The final image with the extracted alteration information is resulted from decomposing mixed alteration information, enhancing the multiple variant alterations and compounding the enhanced image. By comparison 18 remote sensing anomalies are caused by the known gold deposits and the other three anomalies have provided to the national mineral resources survey project. |
