摘要:
提要:笔者根据地壳表层构造与深部构造相结合原则,提出岩石圈构造单元划分应遵循的6条原则。根据地质和地球化学,特别是地球物理场所显示的特征,以贺兰山—川滇南北构造带为界,初步把中国大陆及邻近海域划分为中亚岩石圈构造域和东亚岩石圈构造域2个一级岩石圈构造单元,并进一步划分出6个二级构造单元:西域岩石圈块体、青藏岩石圈块体、松辽岩石圈块体、华北岩石圈块体、华南岩石圈块体、南海岩石圈块体,分别阐述了它们的地质、地球物理、地球化学主要特征。最后,就岩石圈构造单元划分的几个问题进行了探讨,提出一些看法。

Abstract:
Abstract: In light of the principle of combining the Earth's surface tectonics with deep tectonics, the paper proposes six principles that should be followed in the lithospheric tectonic unit division. Based on the geological and geochemical characteristics, especially the characteristics shown by the geophysical field, with the Helan Mountains-Sichuan-Yunnan latitudinal tectonic belt as the boundary, the authors preliminarily divide continental China and its adjacent sea areas into two first-order lithospheric tectonic units: the Central Asian lithospheric tectonic domain and East Asian lithospheric tectonic domains, which are subdivided into six second-order lithospheric tectonic units: the Xiyu lithospheric block, Qinghai-Tibet lithospheric block, Songliao lithospheric block, North China lithospheric block, South China lithospheric block and South China Sea lithospheric block. Their main geological, geophysical and geochemical characteristics are described separately. Finally, some problems concerning the lithospheric tectonic unit division are discussed and some views are presented.
