Remote Sensing Interpretation and Metallogenic Prediction in the Metallogenic Belts of East Kunlun and Altun Mts.

Remote sensing technology can getspectral information and tectonic information effectively and predict the ore-forming areas by extracting the remote sensing anomaly information from macroscopic view and multi-angles.In this paper,the authors have taken the metallogenic belt of East Kunlun and Altun mountains as an example,extracted the alterative anomalies information and tectonic information about the mineralization and ore-controlling structures by the use of image correction,pseudocolor composite and color spatial conversion,image enhancement,mask processing,image fusion,image mosaic,geological information comprehensive analysis and so on,established the prospecting model of remote sensing according to the alterative anomalies information,linear structure and ring structure,and carried out the metallogenic prediction in east Kunlun and Altun Mts.with the multi-source information technology.
