Remote Sensing Prospecting Prediction of Porphyry Copper Deposit in Kahucuo Region of Tibet

Kahucuo is located in the west part of the third porphyry copper belt-the Bangong Lake-Nujiang metallogenic belt in Tibet,which possesses enormous resource potentiality and where large-scale copper-polymetallic deposits,such as Duolong,Gaerqiong,had been discovered in recent years.In order to further expand its copper mine resources,this paper interprets remote sensing geological characteristics of mineral products and extracts remote sensing altered information using ETM+ remote sensing data in this area.By comparing the metallogenic elements of Duolong copper mine and prediction elements and through an integrated analysis,the paper concludes thatline,ring,belt and altered informationare the remote sensing prospecting elements,and delimitates eight prospective areas of mineral exploration.
