根据地质和地球物理特征表现出的岩石圈不连续 ,华北地区可区分出鄂尔多斯克拉通型、燕山太行造山带型和华北平原裂谷型三类岩石圈。依据岩石学方法、壳幔演化模型、造山带形成过程以及地震波速与岩石化学成分之间的关系 ,建立了华北地区三类型岩石圈的壳幔岩石学结构和化学结构 ,讨论了不同岩石圈类型的壳幔物质结构、地壳和岩石圈地幔厚度的地质含义、岩石圈不连续在划分岩石圈单元中的作用及不同类型岩石圈形成的大陆动力学意义。
According to the geological and geophysical characteristics of the lithosphere is not continuous, North China can distinguish Ordos Kratong, Yanshan Taihang orogenic belt and North China Plain three types of lithosphere. Based on the petrology method, the crust-mantle evolution model, the orogenic belt formation process and the relation between seismic velocity and petrochemical composition, the crust-mantle petrological structure and chemical structure of three types of lithosphere in North China are established, and the relationship between lithospheric types The crust-mantle material structure, the geological implications of crust and lithospheric mantle thickness, the role of lithosphere discontinuities in the division of lithospheric units, and the continental dynamics of different types of lithosphere formation.
