摘要 应用Hyperion高光谱数据,通过比值法和最小噪声去除法(MNF)提取了甘肃岌岭701地区的赤铁矿化碱交代蚀变岩的分布。选择最小噪声去除后的主成分MNF b8、b3和b4组合可以增强赤铁矿化碱交代蚀变岩的信息,并填绘出该地区赤铁矿化碱交代蚀变岩的分布。 The hematization alkalic-metasomatic rocks are detected with Hyperion data by the method of band ratio and minimum noise fraction(MNF) in 701 area of Jiling,Gansu.The band composition of MNF b8、b3 and b4 can highlight the information of the hematization alkalic-metasomatic rock and can be used to map the alteration rocks.
