Abstract  

Authors applied the principal component integretion of different band radio images to enhancing hydro-thermal alteration information and developed a new method for extracting mineralized information from Landsat TM data in volcanic rock area covered by vegetation, moist subtropical zone. On trial, great successes have been achived in Bamao Au and Ag multimetal mineralized area, Xinchang County, east Zhejiang province. Not only are the known altered zones in the mineralized area displayed effectively, but also several unknown hydrothermal altered zones, silicified quartz veins, ore-ccontro- lling structures and volcanic apparatuses, which are very useful for mineral prospecting, are revealed here.
