摘　　要：火山岩地区含羟基(OH^-)粘土化蚀变带的识别和圈定是寻找中低温型金属、非金属矿产的重要标志.笔者运用一种定向主成份分析方法于卫星 TM 数据的处理,在浙江东部植被覆盖率为70—80%的中生代火山岩区制得了粘土化蚀变信息增强图像,效果良好.In the volcanic rock area,to identify and to circle clay alteration zones which contain OH^- is very useful for geological exploration such as finding middle and lower temperature rental or non—metal ores,the author used a orientated component analysis method into TM image treatment for processing Landsat TM data,and successfuly made a clay alteration zone enhancement image in the eastern zhejiang province with a total about 70—80% of vege- tation coverage.

关 键 词：粘土化蚀变 特征吸收 信息增强 主成份分析
