TWO PALEO-OCEANS IN THE LATE PALEOZOIC AND THEIR CONTROL TO BASINS IN CHINA

Two important geologic events took place in China during the Late Paleozoic: the Ancient Middle Asian Ocean underrode and consumed during the Late Devonian to Early Carboniferous, and the Xing-Meng orogenic belt combined the Ancient China and the Siberia Plates into the giant Ancient Asian Plate; the Palaeotethys expanded and the SES edge of ancient Asia detached. 3 types of prototype basin were generated in the Ancient Asian Craton from the Late Peleozoic to Triassic: 1)convergent edge basin, mainly in the southern edge of D₍₂₊₃₎-C North Plate, one side or both sides of the D-C central orogenic belt, and the southern of P₂-T South China Plate; 2)detached edge basin, distributed in the southern and northwestern edge of South China Plate and the southern edge of Tarim basin; 3)inner Craton basin, including inner platform depression, fault-depression or fault, rift and aulacogen from remaining basin.
