Based on the fact that the essential factor of time-space distribution and metallognesis of Yunnan, tin deposits is tin-forming granite,and the granites and tin deposits are located by tectogenesis, the authors apply the tin metallogenic theory and the concepts of granite grade system, ore-forming structure system and the mineralization unit of deposits distribution to the research on the remote sensing geological model for tin deposits. Through the comprehensire analysis on remote sensing images, geology, ore deposits, geochemical and geophysical information of the tin mineraliztion concentrating area, the tinbearing remote sensing images are identified.Based on these images the author sum up the comprehensive imformation feature of remote sensing geology and the marks of tin-bearing remote sensing images. The romote sensing geological prospecting model has been setted.Taking the feature of remote sensing image as the trace of recognizing tin-bearing image,combining the image information with geologic environment,and carrying out the comprehensive identification of geoscientific information,all those are the important ways of recognizing the marks of tin-bearing images.The serial models of remote sensing geological prospecting for tin deposits in Yunnan involve the tin-bearing general feature model, deposit locating optimum model and image-geology identification program model.
