摘要
利用ENVI4.7遥感软件,通过比值法和主成分分析法提取了攀枝花地区主要矿区相应的5种蚀变,以此帮助分析和研究该区的钒钛磁铁矿矿化地段。经过后期野外实地踏勘证明,利用遥感影像提取蚀变来帮助圈定靶区和找矿是一种迅速、准确且切实可行的方法。
In this paper,the author used ENVI4.7 remote sensing software as the processing tool,through ratio method and Principal Component Analysis to extract the five kinds of corresponding alteration,to help to research and identify the areas of vanadium titanium magnetite mineralization in this region.In the end,through the field reconnaissance,it can be found that extraction of alteration is a rapid,accurate and practical method to identify and prospect deposit target.
