中文摘要:中国大陆是由众多微陆块和小陆块组合而成的复合大陆，微、小陆块的软碰撞和多旋回缝合以及由此而产生的多旋回复合造山带、多旋回叠合盆地和多彷回构造岩浆成矿作用是其非常重要的特征。中国大陆具有清晰的多旋回分阶段演化过程和复杂的多层次镶叠式与立交桥式结构。古生代以来，中国大构造发展受古亚洲洋、特提斯洋、太平洋三大全球性动力学体系之控制。其主要动力过程表现为冈瓦纳裂离、陆块北移、褶皱带南迁、亚洲增生。

The Continental Tectonics of China

Abstract:The Chinese continenti is a composite continent made up of many blocks of various sizes.It features soft-collision and polycyclic suturing between the blocks and resulting composite orogeny.The continent has distinctively polycyclic evolution by stages and multilevel mosaic and flyover-type structures.Since the Paleozoic,the tectonic development of China has been controlled by the three global dynamic systems——the Paleo-Asian,Tethyan and Pacific systems.The geodynamic processes were marked by Gondwana dispersion,block northward drifing,fold belt southward migration and Asian accretion.
