| 摘 要： | 本文以板块构造理论为主线，应用最新的物探成果和钻井资料，分析了前古生代塔里木盆地地球动力学背景和寒武－奥陶纪、志留－泥盆纪、石炭－二叠纪板块构造演化所形成的盆内隆坳构造格架与沉积特征，认为古生代克拉通原型盆地的发育、各时期的沉积相带分布与沉积建造以及下古生界东厚西薄、上古生界东薄西厚的厚度特征，都是不同地质时代构造演化控制的结果。

| Abstract: | Between Tianshan and kunlun Aerjin Mountains lies Tarim Basin,the largest sedimentary basin in china. The basin has undergone the formation of basement during pre Sinian and development since Phanerozoic and it is a giant complex basin with the histry of a Paleozoic original craton basin overlain by a Mesozoic Cenozoic foreland basin. The craton basin had been subjected to a rift in Sinian,a marginal aulacogen in Cambrian Ordovician and an intracratonic depression basin in Silurian Permian. The Paleozoic Erachem is mainly a set of carbonate rocks and clastic rocks of marine facies and the sedimentary and depressing centers experienced several times of shifting during Paleozoic. The Louer Paleozoic is thicker in the east than in the west and the Upper Paleozoic is thinner in the east than in the west. All resulted from the control of the plate evolution and tectonic framework in Paleozoic. |
