【摘要】 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。更多还原

【Abstract】 Based on lithosphere discontinuity revealed by geological and geophysical characteristics of North China, the authors recognized three kinds of lithospheres in North China region, they are cratonic type lithosphere in Odros, orogenic type lithosphere in Yanshan-Taihang and rift type lithosphere in North China plain. According to petrological means, crust-mantle evolution models, the process of orogenic belt formation, and the relationship between seismic velocity and petrochemical composition, this paper has set up the crust-mantle petrological and petrochemical lithospheric structures of craton, orogenic and rift types in North China. Some important problems are also discussed in this paper, such as the geological implications of the crust-mantle structures and the thicknesses of crust and subcontinental lithospheric mantle in different types of lithospheres, the role of lithospheric discontinuities in the classification of the lithospheric units, and the continental dynamic significance of the formation of different types of lithospheres.更多还原
