| Abstract: | Based on recent field and in door researches and investigations, this paper briefly states and reviews on some issues on the characteristics of the Paleozoic ocean continent transition from Tianshan mountains such as the Precambrian ocean continental framework , opening and closing ages of the Paleozoic ocean, Paleozoic ocean continental framework , the discovery of collision orogenic mollasse formation in the bottom of Lower Carboniferous and its significance , and geodynamic background of formation of Carboniferous Permian large scale rift magmatism And then , some news thoughts about theseissues are put forward |
