    Abstract:

    Study of the Cenozoic paleoaltitude on the Tibetan Plateau is a hot spot,difficulty and focus of the earth system research.It is a key to solve the relationship among the deep earth dynamics,topography evolution and climate change.However,it is still in hotly dispute about the Cenozoic tectonic uplift history.This paper summarized 78 results of the research on the paleoaltitude of the Tibetan Plateau and discussed its current situation.Meanwhile,pointed out the existing characterisrics and problems,and finally discussed the prospects and suggestions for the follow-up paleoaltitude research.Methods: Analyzed the application principles of some palealtitude indexes and their advantages and disadvantages;Collected and summarized the results of the research on the Cenozoic paleoaltitude of the Tibetan Plateau.Results: Collected 78 items of the paleoelevation research on the Cenozoic Tibetan Plateau and pointed out the research history and current status of the paleoelevation.In addition,eight characteristics and problems about the paleoelevation research were stated briefly,namely strata chronology, coordination of oxygen isotope and paleontological paleoaltimeter results,“from a local point record to area”,degree of regional research varying greatly, ambiguity of the surrogate indexes,influence of paleolatitude,uncertainty of the temperature lapse rates in geological time,effect of the global temperature change.Conclusions: In the future paleoelevation work,following items had better to be noticed: paying attention to the reliability of the strata chronology; applications of multidisciplinary comprehensive methods;more research on the Central Northern Tibetan Plateau;develop new paleoaltimeters;make full use of the results got from other disciplines;combine geological evidence and simulation model.
