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.
