摘要
Pangxidong area was chosen as the study area, according to the spectral characteristics of the altered rocks,based on ETM+ remote sensing data, the enhanced processing methods were used such as principal component analysis, band radio and density separation to extract alteration information. Geological data were integrated with the result of remote sensing image processing to delineate prospecting targets and provide reference for further exploration.
