摘要:
提要:国内外不少学者认为中国东部中生代岩石圈演化与太平洋板块向欧亚大陆俯冲、消减有关,近年来作者从岩石圈–软流层深部地质过程审视中国东部岩石圈演化问题发现,中国东部中生代早期(三叠纪至侏罗纪)岩石圈演化与太平洋板块向欧亚大陆俯冲消减没有直接的关系,它们可能是一种源自中国东部周边东亚洋盆系的一些洋盆向中国东部大陆俯冲消减碰撞造山以及由它们引发的中国东部大陆内的软流层上涌的深部地质作用联合作用的结果。软流层上涌作用自始至终控制着中国东部大陆岩石圈与软流层之间以及壳幔之间的层圈拆离,底侵作用以及岩石圈变形缩短、伸展和岩浆活动。

Abstract:
Abstract:Many scholars at home and abroad believe that lithospheric evolution was related to the subduction of the Pacific plate to the Eurasian plate in eastern China in early Mesozoic. In recent years, the authors examined lithosphere evolution in eastern China from the lithosphere –asthenosphere deep geological process and found that early Mesozoic lithospheric evolution and the subduction of the Pacific plate to the Eurasia plate had no direct relationship, and they might have been the results of the joint action, i.e., the subduction of some oceanic basins of the East Asian seas that originated in China’s eastern periphery to the eastern China continental and collisional orogenic belt and the asthenosphere upwelling caused by such actions. From the beginning to the end, upwelling asthenosphere controlled the layer ringed detachment between the lithosphere and the asthenosphere and between the crust and the mantle, the underplating, and the lithospheric deformation, shortening and extension as well as magmatic activities.
Key words:  upwelling asthenosphere  the Pacific plate, lithosphere evolution
