通过对青海茫崖地区蚀变岩和矿化围岩的光谱测试,以及光谱特征分析,采用基于光谱特征的遥感找矿信息增强处理技术,直接从TM图像中提取与金属矿化有关的蚀变信息,结合区域地质背景与成矿条件,进行试验区的成矿预测与靶区圈定,取得了很好的实际应用效果。 更多还原
【Abstract】 Based on the test and analysis on spectrum feature of alterative rock and wall rock, alteration information related to mineralization was directly extracted and enhanced from TM remote sensing image. Combining with regional geological background and mineralizing condition, ore prediction and target area outlining in the test region was carried out.A good application effect is obtained 更多还原
