| 摘 要： | 通过对塔里木盆地前震旦-石炭纪构造演化与地层组合特征的分析研究,将该盆地构造和地层系统划分为2大组合系统5个构造-地层组合.前震旦系为混合片麻岩、浅变质岩组成的地台基底,震旦纪发生板内裂陷形成坳拉槽,早寒武世-奥陶纪和石炭纪是盆地两次大的海侵期,沉积了富含烃类的碳酸盐岩建造,志留-泥盆纪为克拉通边缘隆升阶段,发育浅海相碎屑岩及碳酸盐岩建造.

| Abstract: | This paper discusses the stages of tectonic evolution from pre sinian to carbonifeous and the characteristics of stratigraphy assemblage of Tarim basin. According to the characteristics of structure and sedimentation of Tarim Basin, it can be divided into two assemblages and five assemblage characteristics. Pre sinian basement consists of mixed gneiss and slightly metamorphic rock. The plate rifted in sinian to form aulacogen. In early Cambrian to Ordovician and Carbonifeous, two major transgressions occurred and hydrocarbon enriched carbonate formation deposited. Margin rise of craton from silurian to Devonian, it developed shallow marine clastic rock and carbonate formation deposited. |
