青藏高原的地幔动力学研究

青藏高原的形成是印度板块与欧亚大陆碰撞、挤压的结果，但简单的碰撞模型及南西—北东向的挤压无法解释高原现今所有的构造。因此，其他地球动力学因素，尤其是地幔动力学过程逐渐引起人们的关注。简要回顾青藏高原隆升的地幔动力学机制研究历史；较详细地介绍了青藏高原下深部结构的地幔动力学含义；并重点评述在青藏高原隆升的地幔动力学机制研究领域所取得的主要结果。说明在全球构造格局中，青藏高原不仅仅是印度和欧亚大陆会聚、碰撞以及大陆形变的结果，它也是青藏高原大陆岩石层和下伏地幔物质运动的相互耦合、相互作用的产物。

A STUDY OF MANTLE DYNAMICS OF THE TIBETAN PLATEAU

The uplift and formation of the Tibetan Plateau is the dynamic consequence of the collision between the Indian and Eurasian plates. However, the collision model alone and the South-north compression between two plates cannot clarify all the tectonic features of the plateau. Therefore, other dynamic processes, especially that within the mantle draw the attention gradually. The research history on the mantle dynamic mechanism of the uplift of Tibetan Plateau is reviewed briefly and the mantle dynamic implication of the deep structure beneath the plateauin reviewed in detail. We concentrate on introducing the progress of the study on mantle dynamic mechanism of the uplift of Tibetan Plateau. It is proposed that the Tibetan Plateau is the consequence of not only the collision between India and Eurasia plates, but also the coupling and interaction between the lithosphere and underlaying mantle of the plateau.
