摘　　要：将塔里木盆地寒武纪-二叠纪划分为3个沉积体系组(分为海洋,海陆过渡和陆相体系组),并进一步识别出11个沉积体系分别为冲积扇相、河流相、三角洲相、湖泊相、滨岸相、局限台地相、开阔台地相、台地边缘相、台地边缘斜坡相、陆棚相、盆地相。沉积相分布特征在各个时期存在差异性,但在整个沉积演化过程中,又具有继承性。The author divides Cambrian-Permian , Tarim basin into three depositional systems group （ marine , sea-onshore, continental）,and further identifies to 11 sedimentary systems ： alluvial fans facies.fluvial facies.the delta facies .lakes.lacustrine facies.littoral facies.wide mesa facies.mesa edge facies.edge slope facies.basin facies and turbidite facies. Research shows that distribution characteristics of sedimentary faces differs in each time, but also exists the inheritance in the entire sedimentary evolution process.
