摘要: 提要：运用地体和地体活动论观点，提出青藏高原结构划分的新方案；强调青藏高原的形成经历了新元古代以来长期活动的过程，青藏高原是一个“非原地”诸多地体会聚、拼合以及经历复合碰撞造山的“造山的高原”；大型走滑断裂在青藏高原形成中起着地体相对位移、侧向挤出、移置及使高原几何形态扭曲的作用。提出青藏高原隆升的 “南缘超深俯冲（>600 km）、北缘陆内俯冲、腹地深部热结构及岩石圈范围内的向NE右旋隆升”的多元驱动力机制。Abstract: Abstract:Recent studies on the compositions and structures of multiple terrains within the plateau have offered us an QinghaiTibet opportunity to examine how this plateau was assembled in the context of terrain tectonics. The formation of this plateau resulted from tectonic activities since the late Longterm Paleozoic which is represented by (1) convergence and welding of A number of exotic terrains, and (2) collision induced "orogenic plateaux" and has reached its climax in the Cenozoic. faults (commonly Largescale Strikeslip act as terrain boundary faults) has played a central role in controlling the relative offset, magnitude of lateral extrusion, and the geometry of these terrains. The final assembly and rise of the QinghaiTibet Plateau May result from a combination of contemporaneous processes, e.g. Superdeep subduction (> 600 km) at its southern margin subduction at its northern margin, Intracontinental Inland, deep thermal processes, and lateral uplift of mantle lithosphere.
