| 摘 要： | 综合分析了前人对青藏高原岩石层构造和动力学研究的成果，提出印度板块和欧亚板块会聚、大陆碰撞及大陆形变的基本特征为青藏高原地壳的加厚和地壳缩短，地壳物质的横向流动；青藏高原隆升过程呈现出阶段性、多样性和复杂性；组成青藏高原的各块体可能有不同的主导隆升机制．认识到在板块构造理论所揭示的全球构造格局中，青藏高原不仅仅是印度板块和欧亚板块会聚、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、相互作用的结果．从地幔动力学的角度出发讨论了青藏高原隆升的断离险升－挤压隆升－对流隆升三阶段模式（ＢＣＣＭ），结合数值模拟的结果分析了与此模式相对应的该区域岩石层构造、运动的地幔深部物质运移和动力学背景．

| Abstract: | The basic features of the lithosphere structure and movements of the TibetPlateau after the collision between India and Eurasia Plates are summarized in thispaper. They are the crust thickening, crust shortening and the horizontal material flowin the crust. The plateau's uplift is a multi-phase and multi-style process. There aredifferent dominant uplift mechanisms for different geological blocks composed theTibet Plateau. A three stage uplift model of the Tibet Plateau, Breakoff uplift-Compression uplift-Convective uplift Model (BCCM), which suggested by Fu et al., isdiscussed and investigated with a numerical model resultS. It is to be supposed thatthe Tibet Plateau is not only the consequence of the collision between india andEurasia Plates, but also is the consequence of the coupling and itheraction betweenthe lithosphere and its underiaying mantle in this region. |
