Abstract: Between Tianshan and kunlun一Aerjin Mountains lies Tarim Basin, the largest sedimentary basin inchina. The basin has undergone the formation of basement during pre Siian and development sincePhanerozoic and it is agiant complex basin with the histry of a Paleozoic origina lcraton basin overlain bya Mesozoic-Cenozoic foreland basin. The craton basin had been subjected to a rift in nian, a marginalaulacogen in Cambrian-Ordovician and an intracratonic depression basin in Silurian-Permian. The Paleo-wic Erachem is mainly a set of〔arbonate rocks and clastic rocks of marinefacies and the sedimentary anddepressi ng centers experienced several times of shifting during Paleozoic.The Louer Paleowic is thickerin the east than in the west and the Upper Paleozoic is thinner in the east than in the west. All resultedfrom the control of the plate evolution and tectonic framework in Paleozoic.
