| 摘 要： | 塔西南坳陷自中生代早期以来进入陆相沉积发育阶段，由于天山隆升及昆仑山的俯冲，塔西南地区侏罗地区侏罗系表现出西岸陡、东岸缓的断陷盆地特征。研究表明，侏罗纪断陷湖盆共发育Ｇｍｓ，Ｇｍ，Ｇｔ，Ｇｐｂ，Ｇｐ，等１９种岩石相类型和冲积扇相、扇三角洲相、辫状三角洲相、正常三角洲相及湖泊相等５种沉积相类型。西岸陡坡带以冲积扇和扇三角洲沉积为主，东岸缓坡带以河流三角洲、辫状三角洲占优势，盆地中心为湖相沉积。不同的 |

| Abstract: | The development of terrigenous sedimentation occurred in the depression of southwest Tarim in the early Messozoic period.The uplifting of Tianshan and subduction of Kunlunshan brought about a fault basin with the attitude of Jurassic stratum steep in the west and gentle in the east.Research showed that 19 types of lithofacies and 5 types of sedimentary facies were developed in the Jurassic fault basin.The major sedimentary facies were alluvial fan facies and fan delta facies in the west,and stream delta and braided delta in the east,with a lacustrine facies in the centre of the fault basin.Different sedimentary facies with different lithofacies formed in different stages of basin development. |
| Keywords: | lithofacies sedimentary facies fault basin southwest Tarim depression |
