摘要:

根据国内外最新地球物理和其它地学资料,采用多学科多手段进行综合反演,建立中国及邻区高分辨率地球三维结构模型,为地学各领域提供高精度多参数地球三维模型数据库。对中国及邻近陆域海域岩石圈软流圈结构,过渡带以下直至核幔边界的地幔速度三维分布进行研究。探讨东亚及西太平洋边缘海板块运动、地幔对流、圈层耦合及物质运移等深部动力学问题。对中国大陆及边缘海各地块的结构及相互作用,特别是有关中国东部及边缘海岩石圈拉张减薄、西部岩石圈汇聚增厚的深部动力学过程作了探讨。

关键词: 中国及邻近陆域海域地球圈层三维模型地球深部动力学    
Abstract:

    The continent of China and its adjacent land and marginal seas were formed by convergent and collided of a series of sub-plates and blocks in the late Paleozoic. Since Mesozoic the lithosphere in east part of east Asia was broken up and thinning,the asthenosphere upwelling forming the giant rifts system,whereas in west part the Indian lithosphere collided with Eurasia in Paleocene causing the crust to be shortened and uplifted. The structure and evolution of lithosphere are very complicated.
    We collected the newly geophysical data and other geospaces data in China and adjacent land and sea regions for inverting the fine three-dimensional structures Earth model with multi-discipline researches and various inversion methods. The high-resolution three-dimensional Earth model and database in the area will be built and provided a reference model for applied in individual geosciences fields.
    It aimed to discover the structure of lithosphere and asthenosphere,the three-dimensional velocity and physical properties in transition zone to core-mantle boundary. To study the interactions between sub-plates and blocks of lithosphere,the deep dynamic processes of the mantle convection,layered coupling. A detail discussion has been made for the structure and interaction of lithospheric blocks,especially for the deep dynamic processes collision and thicken of lithosphere in west part and the extension and thinning in east part.

Key words: Deep geodynamics.    China and its adjacent land and sea regions    Three-dimensional layered Earth’s model
