Correspondingly, basins in the region evolved from the marine basin of Sinian to middle Triassic,the arround Yangtze foreland basin of late Triassic to middle Jurassic, volcanic basins of late Jurassic to early Cretaceous to extensional basins of late Cretaceous to Eogene. The marine basin of Sinian to middle Triassic in the region was developed on the passive, extensional continental margin. The around Yangtze foreland basin occurred in a foreland deformation belt caused by the collision between the Yangtze and North China plates. The volcanic basins were developed under the setting of regional strike slip and circum Pacific magma arc. Westward, low angle, high speed subduction of the Kula-Pacific plates resulted in lithosphere uprising and tension, leading to development of the extensional basins. With the presence of back arc basins on the western margin of the Pacific Basin as well as collision between the Indian and Eurasian plates, East China continent was subjected to E-W compression and the basin evolution was therefore ceased.Read More
