Theoretical Prediction and Scientific Exploration: The Gangdese Porphyry Copper Deposits in Tibet as An Example

LI De-wei a,b (a.Faculty of Earth Sciences;b.Research Center of the Qinghai- Tibet Plateau,China University of Geosciences,Wuhan 430074,China)  
Many large and superlarge porphyry copper deposits found in the Gangdese tectono-metallogenic belt, Tibet in the recent years were formed by intraplate uplift processes of the Qinghai-Tibet plateau during 17—15 Ma.The type,scale,location and era of the deposits are in accordance with the results theoretically forecasted ten years ago. According to the new ideas of continental dynamic and metallogenic dynamics rather than traditional model of plate collision orogeny and plate collision metallogeny,the author suggests that the Gangdese porphyry copper deposits could have been formed by dynamic reformed metallogeny processes related to late Cenozoic tectonic uplift,laminar flow of lower crust,intraplate orogeny, crustal thickening,thermal uplifting extension after tethys closure,plate collision epeirogeny.To strengthen basic geology study, to the innovation of scientific thinking to develop geologic and metallogenic theory plays a major role in exploration of West China.
