| 摘 要： | 印度板块与欧亚板块的碰撞是新生代全球最重要的地质事件，由此青藏高原快速隆升，成为了世界第三极，并不断向外扩展，其内部大型断裂体系发育、地质构造复杂、地震及火山活动性强烈。青藏高原东部及其周边地区作为研究高原隆升、深部变形的动力学机制的天然试验场，也是国际地学领域、地球物理与大陆动力学领域的一个重要焦点。本文根据第八届青藏高原东部构造与地球物理研讨会（WTGTP2020）的学术报告，对高原深部结构与动力学研究的一些新进展进行阐述。本次研讨会对青藏高原及其周边地区岩石圈结构、变形机制及物质运移动力学模式等关键问题进行了较为系统的讨论，围绕青藏高原的形成演化历史，从深部构造与岩浆变质响应，到浅部地表过程以及其对资源气候的影响进行探讨研究，将地球深部动力学、地表过程和气候变化等不同圈层的相互作用有机地联系在一起。

| Abstract: | The collision between the Indian and the Eurasian plates is the most important geological event in the world since the Cenozoic. And the Tibetan Plateau has risen rapidly, becoming the world’s third pole and expanding outward continuously. There are development of active fault zones, complicated geological structure, strong seismicity and volcanic activity. The Tibetan Plateau and its surrounding areas as a natural experimental site for studying the dynamic mechanism of plateau uplift and deep structure deformation, are also an important focus in the fields of geosciences, geophysics and continental dynamics. Based on the academic report of WTGTP2020, this paper expounds some new progress in the study of deep structure and dynamics of the Tibetan Plateau. This seminar systematically discussed topics such as lithosphere structure, structure deformation mechanism, material migration dynamics pattern in the Tibetan Plateau. Based on the formation and evolution history of the Tibetan Plateau, the deep structure and magmatic metamorphic response, the shallow surface process and its impact on resources and climate are discussed. This organically links the interaction of different spheres such as deep geophysics, continental dynamics, surface processes and climate change. |
