摘要:
青藏高原东南缘的岩石圈变形特征和动力学过程显著不同于以正向碰撞为主要形式的青藏高原本体。其变形样式在地壳浅部以侧向滑移为主,并伴随一系列尚待揭示的深部过程。毫无疑问,青藏高原东南缘的岩石圈结构探测研究是理解青藏高原碰撞造山、深部动力学过程不可或缺的重要环节。而揭示与侧向碰撞变形的深部过程相伴生的成矿带的岩石圈三维结构和深部动力学背景,对大陆碰撞成矿理论框架的完整性至为关键。通过对青藏高原东南缘的壳幔结构探测研究成果和基本认识进行了较系统的梳理,重点介绍青藏高原东南缘及邻区深部结构地震学探测研究近十几年的新进展、新认识,主要涉及壳幔结构的天然地震成像、人工源地震探测剖面和深部动力学等研究方向,供对青藏高原地学研究感兴趣的地质科研人员参考。
Abstract:
The deformation feature and dynamic processes of the lithosphere in the southeastern margin of Qinghai-Tibet Plateau are significantly different from the principal part of the plateau, where forward collision is taking as the main form. The deformation patterns of the lithosphere in southeastern margin of Qinghai-Tibet Plateau are mainly characterized by lateral slip on the shallow crust, and accompanied by a series of deep processes to be revealed. Undoubtedly, the exploration and study of lithospheric structure in the southeastern margin of Qinghai-Tibet Plateau are indispensable to understand the deep dynamic process and collisional orogeny of Qinghai-Tibet Plateau. It is crucial to reveal the three-dimensional structure of the lithosphere and deep dynamic background of metallogenic zone associated with the deep process of lateral collision deformation for the integrity of the theoretical framework of continental collision orogeny and mineralization. The research results and basic knowledge of crust-upper mantle structure detection in the southeastern margin of Qinghai-Tibet Plateau are systematically sorted out, the recent progress and new understanding of deep structural seismic exploration in the southeastern margin of Qinghai-Tibet Plateau and its adjacent areas during recent decades are emphatically introduced, mainly in natural seismic imaging, artificial seismic profile and deep dynamics of the crust-upper mantle structure, which can be used as a reference for researchers interested in geosciences of Qinghai-Tibet Plateau.
