    摘要:

    近10年来,"大陆构造与动力学实验室"在青藏高原大陆动力学研究,尤其在特提斯演化和青藏高原生长方面取得若干进展,包括(1)"青藏高原——造山的高原"理念的提出;(2)青藏高原特提斯体制和构造格架的再造;(3)新特提斯蛇绿岩中原位金刚石和深地幔矿物群的重大发现;(4)新特提斯洋盆俯冲新机制的揭示;(5)印度/亚洲碰撞的早期岩浆和喜马拉雅折返中的作用;(6)喜马拉雅三维碰撞造山机制和折返全过程的初步建立;(7)青藏高原东南缘物质逃逸的新机制——"弯曲与地壳解耦"的提出;(8)青藏高原俯冲型、碰撞型及陆内型片麻岩穹窿;(9)青藏高原东缘汶川强震的构造背景和强震机制;(10)青藏高原碰撞造山成矿模式;(11)印度/亚洲碰撞过程的数值模拟。综述和集成上述成果是为了与同行们交流磋商,进一步共同发展青藏高原大陆动力学理论,向国际地学前沿的冲刺。

    Abstract:

    Based on the previously research, the research group of Key Laboratory of Continental Tectonics and Dynamics has achieved lots of great progress in the study of the continental dynamics of the Tibetan Plateau, especially in the evolution of Tethys and the growth of the Tibetan Plateau during the past decade. These achievements can be summarized as follows:(1) The Hypothesis on Tibetan Plateau as a orogenic plateau was proposed; (2) the reconstruction of the tectonic framework and the Tibetan-Tethys system; (3) the discovery of in situ diamond and deep mantle-derived mineral group in the ophiolites distributed along the Neotethyan suture zone; (4) the understanding of the subduction mechanism of the Neotethy oceanic basins; (5) the role of magmatism formed in the early stage of the Indo-Asian collision for the exhumation of Himalaya; (6) the establishment of the 3D models of the collisional orogeny and exhumation of the Himalaya; (7) the new proposal on the extrusion of the SE Tibetan Plateau:‘crustal bending and decouple’; (8) the subduction-related, collision-related and continental gneiss domes with Tibetan Plateau; (9) the tectonic setting and the Wenchuan Earthquake mechanism on the eastern margin of the Tibetan Plateau; (10) Numerical modeling of the Indo-Asian collisional process. This paper aims to communicate with and stimulate interest among global geologists to make further development in the continental dynamics of the Tibetan Plateau.
