摘要
东天山康古尔塔格地区是重要的Au成矿带, 利用该区ETM遥感数据, 运用HIS空间变换和主成分分析技术, 进行数据融合和图像增强处理, 提取了小构造和岩石蚀变信息;通过与矿床 (点)、地层、地球化学异常等信息叠加, ETM+遥感图像能很好的反映韧性剪切带、岩体和蚀变特征. 因此从遥感信息中解译直接找矿信息 (控矿构造与蚀变信息 ) 是有效、经济、快速的地质调查方法.
The Kanggultage area in East Tianshan is an important Au metallogenic belt. Information of structure and rock alteration are extracted from ETM remote sensing data which deal with data amalgamation and image enhancement by HIS space transform and main component analysis. By composing remote sensing with mine, stratum, geochemistry abnormal information, ETM+ data can reflect the properties of ductile shear zone,and rock alteration. The geological survey method is economical and effective from remote sensing data translate to immediacy information of prediction of mineral resources.
