对青藏高原隆升研究的几点思考

青藏高原的隆升机制和隆升历史,需多学科参与.其研究思想和研究方法有几点值得思考:①磨拉石与高原(地面)隆升有没有必然的关系；②生物尤其是古植物对青藏高原隆升最具灵敏性,能够指示青藏高原多阶段隆升的一系列信息,应该是今后研究的重点；③不可忽视加大对高原腹地的沉积盆地研究；④多学科的相互交叉、相互渗透已成为研究青藏高原隆升的必然趋势,并以青藏高原北缘新生代生物、沉积学、岩石学成果为例.这些研究不仅可以极大丰富青藏高原隆升的内容,而且可以相互验证,提供更多相关联的直接证据.

New Considerations in Studies on Uplift of the Qinghai-Tibet Plateau

Studies on uplift and uplift history of the Qinghai-Tibet Plateau demand multidisciplinary participations.The uplift mechanism of the Plateau,a long time debate,is interested by geologists all over the world.According to the recent field geological survey of the authors,we present here some considerations on studying methods and ideas of the uplift of the Qinghai-Tibet Plateau.First,whether or not molasse deposition has certain relationship with the plateau(surface) uplift.Second,biological records,especially palaeobotany,are sensitive to the plateau(surface) uplift,are credible indicators for a series of multi-phased uplifts of the Tibet plateau.Third,intercross of multi-subjects researching is needed to disclose the complete uplift history of the Qinghai-Tibet Plateau in Cenozoic era.Fourth,more emphasis should be given in studying the hinterland sedimentary basin of the Plateau.
