摘要: 中元古代末发生的晋宁运动在中国南方扬子陆块的周缘形成碰撞造山带,使华夏、川滇藏等陆块与扬子陆块拼合成统一的华南古大陆,奠定了新元古代—早古生代盆地发育的基底.新元古代—早古生代,中国南方在陆块裂解—离散—聚合不同的构造运动体制下,分别在扬子陆块的边缘和内部形成了不同的盆地原型及其演化序列.在扬子陆块的南、北缘,主要形成了裂陷—被动大陆边缘坳陷—前陆盆地的原型演化序列;在扬子陆内,由陆块离散拉张背景下整体下沉形成的碳酸盐岩台地演化为陆块聚合挤压背景下形成的台内坳陷盆地.而且,经加里东运动后,中国南方大陆得到了新的增生和统一,基本构造格局已经形成.Abstract: At the end Mesoproterozoic,Jinning movement takes place.Collisional orogenic belts generate around the edge of Yangtze block in South China.Huaxia block and Sichuan-Yunnan-Tibet block collide with Yangtze block and form South China ancient continent,founding basement for basin generation from Neoproterozoic to early Paleozoic.From Neoproterozoic to early Paleozoic,South China experiences series of tectonic evolution as "block rift,divergence and convergence",and forms different basin prototypes with different evolution histories around and in Yangtze block.At the southern and northern edge of Yangtze block,basin prototype evolution process is from rift,passive continent margin depression to foreland basin.In Yangtze block,carbonate platform deposited under block divergeoce and extension background develops to intraplatform depression basin formed uoder block convergence and compression background.After Caledonian movement,South China continent has been newly accreted and unified and the basic tectonic pattern has been formed.
