摘要
中国大陆及邻近陆域海域是晚古生代以来由多个较小的板块或地块汇聚形成的。中生代亚洲东部岩石圈拉张解体和减薄。古新世印度板块与欧亚板块碰撞引起地壳缩短隆升,形成青藏高原和喜马拉雅造山带。根据中国大陆及相邻区域天然地震、人工地震及其他地学资料,采用多学科多手段进行反演。对沉积层、地壳、岩石圈厚度进行研究,探讨中国大陆及相邻陆域海域岩石圈结构特征及深部动力学问题。
The continent of China and its adjacent lands and marginal seas were formed by convergent and collidsion of a series of sub-plates and blocks in the late Paleozoic. Since Mesozoic, the lithosphere in the east part of China was broken up and thinning down, the asthenosphere upwelling forming the giant rifts system, whereas in the west part, the Indian lithosphere collided with Eurasia in Paleocene to cause the crust to be shortened and uplifted. The structure and evolution of lithosphere are very complicated. The authors collected the data of explosion seismic profiles and inversion by surface wave and body wave, and other geosciences data in China and adjacent land and sea regions for studying the structures of lithosphere. The map of the thickness of lithosphere, crust, sedimentary basin compiled to discuss the geodynamics of lithosphere.
