中国古生代盆地基底大地构造特征

太古宙(>2 500 Ma)是出现陆核或形成初始陆块的阶段。华北和塔里木是最早出现初始陆块的地区。古元古代(1 800~2 500 Ma)为陆块迅速增生阶段;古元古代末,华北、塔里木、柴达木和扬子陆块经增生相互联接。中元古代(1 000~1 800 Ma)为裂谷发育阶段,在古元古代末相互联接的地区重新发生裂解,分裂为华北、塔柴和扬子陆块。晋宁期末,华北、佳木斯、塔柴、扬子、华夏及滇藏陆块相互拼合,成为Rodinia超大陆的组成部分。新元古代初(<1 000 Ma),在古板块运动体制下,形成中国新元古代—古生代盆地。 

THE BASEMENT TECTONIC CHARACTERISTICS OF THE PALAEOIC BASIN,CHINA

The Archaeozoic Era(2 500 Ma) is the stage that the continental nucleus occurrs or the proto-continental segment forms.The proto-continental segments firstly occurred in the North of China and(Tarim.) The Paleoproterozoic(1 800～2 500 Ma) is the stage that the continental segments rapidly accrete.The North china,Tarim,Qaidam and Yangtze continental segments were connected by accretion in the end of Paleoproterozoic Era.The Mesoproterozoic (1 000～1 800 Ma) is the stage that the rifts develope.The continental segments which have been connected by accretion in the end of Mesoproterozoic were re-broken up into the North China,Tarim-Qaidam and Yangtze continental segments.In the end of Jinning stage,the North China,Jiamusi,Tarim-Qaidam,Yangtze,Cathaysia and Dian-Zang continental segments integrated each other,becoming a part of Rodinia Super Continent.Beginning from the Neoproterozoic(<1 000 Ma) to Palaeozoic Era,the Chinese Neoproterozoic-Palaeozoic basins formed under the Palaeo-plate tectonic system.
