摘　　要：本文重新审视了青藏高原的关键科学问题,为解决板块构造理论的"登陆"难题提供新的线索,为理解板块汇聚边界的大陆岩石圈演化及其能源资源、地质灾害和全球环境效应提供新的思路。本文探讨了青藏高原如下十大关键地学问题:(1)印度大陆北漂模型;(2)印度-亚洲初始碰撞时限;(3)青藏高原的古特提斯造山作用;(4)古近纪喜马拉雅造山带的地壳缩短;(5)高喜马拉雅的深熔机制;(6)青藏高原隆升的时限和差异性;(7)构造-剥蚀-气候相互作用与南亚季风;(8)青藏高原关键矿产资源的分布与成因;(9)青藏高原的活动断裂带与孕震机制;(10)碰撞后的印度板块何去何从——深部动力学过程。这些问题可以作为当前研究青藏高原大陆动力学演化的重点方向。In this paper, the authors re-examine the key scientific issues concerning the evolution of the Tibetan Plateau, in order to help the sea-born plate tectonic to “land”. We also aim to provide new information for the study of continental lithosphere evolution in convergent margins, as well as energy resources, geological hazards and global environmental effects of these regions. The authors summarize ten key geoscientific issues as follows:(1) drifting process of the Indian Continent;(2) timing of initial India-Asia continental collision;(3) Paleo-Tethys Orogeny in the Tibetan Plateau;(4) crustal shortening of the Eo-Himalaya;(5) anataxis mechanism of the High Himalaya;(6) timing of the uplift of the Tibetan Plateau;(7) relationship between the Asian monsoon and the geodynamic evolution of the Tibetan Plateau;(8) distribution and genesis of the new energy mineral resources in the Tibetan Plateau;(9) active fault zones of Tibetan plateau and their seismogenic mechanism;(10) deep geodynamics discussion: where goes the post-collisional Indian plate? The authors hope these discussions would inspire new ideas to study the continental geodynamics of the Tibetan Plateau.
