Applications of Low Temperature Thermochronology in the Tectonogeomorphology Evolution of the Tibetan Plateau

The tectonogeomorphology is regarded as the key to understanding the uplift history of the Tibetan Plateau. But its research is blocked by the poor constrains of chronology. The low temperature thermochronology, the most fashions are the zircon and apatite fission-track and (U-Th)/He thermochronology (ZFT, AFT, ZHe and AHe), has thoroughly developed recently, become a sensitive and precise tool for this kind study, and was suggested in this paper. A metasynthesis study of the multiple low temperature thermochronology was proposed, including the bedrocks of high altitude mountains, on which low-relief and layered landscapes has developed and relicted, as well as the synorogenic deposits, such as the Cenozoic sediments, river terraces and modern river deposits. Thus, mutual compensation of advantages among ZFT, AFT, ZHe and AHe could be achieved to yield a whole exhumation and evolution history of regional tectonogeomorphology during the Cenozic. Accordingly, several conceptual growth models of the tectonogeomorphology terrane can be yielded. However, issues as pointed out in this study are still exist when conducting the relevant researches, and should be carefully addressed.
