| 摘 要： | 塔里木盆地上泥盆统及石炭系包括5个组，自下而上分别为上泥盆统东河塘组和甘木里克组，石炭系巴楚组、卡拉沙依组和小海子组。其中东河塘组和甘木里克组地质时代为晚泥盆世，巴楚组地质时代为早石炭世杜内早中期，卡拉沙依组地质时代为晚杜内中期至巴什基尔期，小海子组地层时代为巴什基尔末期至莫斯科早期。岩石类型有碎屑岩和碳酸盐岩，还有膏盐岩，并夹薄层火山碎屑岩。沉积相主要为海陆过渡相组合，包括河流、三角洲、滨岸、浅海、碳酸盐岩台地、台地边缘6种相和12种亚相及33种微相。晚泥盆世东河塘期至石炭纪发生过4次较大的海侵，海侵范围由下而上逐渐增大，至晚石炭世小海子期海侵规模最大。东河塘期开始海侵，海水由西而东侵入，此时周缘碎屑物质供应充分，主要为无障壁海岸和障壁海岸沉积，西南缘为浅海相沉积。巴楚期晚期，海侵范围进一步扩大，物源向北或北东方向退却，陆源碎屑物质注入急剧减少，形成了一套富含生屑的碳酸盐岩地层，发育了开阔台地和局限台地亚相沉积。卡拉沙依期中期海侵规模比巴楚期更大，海水深度加大，西部为开阔台地亚相沉积，其余地区为局限台地亚相沉积。卡拉沙依期晚期和小海子期海侵达最大，向东扩展，大部分地区为开阔台地亚相沉积，东部地区为局限台地亚相沉积，塔北大部分地区缺失。

| Abstract: | The Upper Devonian and Carboniferous of Tarim Basin can be divided into Donghetang Formation, Ganmulike Formation, Bachu Formation, Kalashayi Formation and Xiaohaizi Formation. The Donghetang Formation and Ganmulike Formation belong to the Late Devonian, the Bachu Formation belongs to the Early Middle Tournaisian of the Early Carboniferous, the Kalashayi Formation belongs to the Late Tournaisian to Bashkirian, and the Xiaohaizi Formation belong to the Late Bashkirian to Moscovian. There are terrigenous clastic rocks and carbonate rocks in those Formations. There are 6 facies, i.e. fluvial facies, delta facies, littoral facies, neritic facies,carbonate platform facies, platform margin facies. There are and 12 subfacies and 33 microfacies.There were 4 trangressions from the Late Devonian to Carboniferous, and the trangressions happened and increased gradually from east to west. Because of a lot of terrigenous supply, the sedimentary facies were mainly littoral facies and nertic facies during the Donghetang Age. From the Bachu Age to Xiaohaizi Age, the trangression area increased, and the sedimentary facies were mainly carbonate platforms. |
