摘要
Tarim Basin underwent several major evolutionary stages during the Paleozoic,including the periods at the end of the Middle to early Late Ordovician, the end of the Late Ordovician and the end of the Middle Devonian or Early Carboniferous, and resulted in a series of important unconformities. The study show that the deformation occurred at the end of the Middle to early Late Ordovician might have resulted from the northward collision and extrusion of the North Kunlun orogenics. At the end of the Middle Devonian, the intensively uplifting of the Tabei uplifts and the folding and uplifting of the Manjiaer Depression might be attributed to the collision of the southern Tianshan Ocean.
