摘　　要：塔里木盆地西部玛扎塔格山古董山青石沟剖面的石炭系自下而上划分为下统克里塔格组、和什拉普组、上统卡拉乌依组和阿孜干组,以微体化石的分析结果划分为:牙形刺Clydagnathus-Neoprioniodus组合带、Gnatho-dus bilineatus带、Idiognathoides sulcatus-Declinognathodus noduliferus组合带、Idiognathoides corrugatus-Neog-nathodus bassleri组合带、Streptognathodus parvus-S.suberectus组合带;Eostaf fella带、Pseudostaf fella带、Fusulina-Fusulinella组合带;非有孔虫Archaediscus-Earlandia-Endothyra组合带、Globivalvulina-Bradyina-Glomospira组合带。岩相序列和沉积环境分析显示其海相序列与铁克里克地层区的相似程度高。Carboniferous sequence from the Qingshigou section, Gudongshan, Mazatage, Tarim Basin are subdivided into the Kelitag and Heshilafu formations of the Lower Series and Kalawuyi and Azigan formations of the Upper Se- ries in ascending order. Micropalaeontological biozones are recognized. Conodont zones are of the Clydagnathus- Neoprioniodus Assembladge Zone, and Gnathodus bilineatus Zone, Idiognathoides sulcatus-Declinognathodus nodu- li ferus Assemblage Zone, Idiognathoides corrugatus-Neognathodus bassleri Assemblage Zone, and Streptognatho- dus parvus-S, subereetus Assemblage Zone. Fusulinids zones include the Eostaffella Zone, Pseudostaffella Zone, and Fusulina＇Fusulinella Assemblage Zone. Other foraminifera zones include Archaediscus-Earlandia-Endothyra Assemblage Zone, and Globivalvulina-Bradyina-Glomospira Assemblage Zone. Lithofacies as well as sedimentary environmental analysis show that the Mazatag is more likely assigned to the Tiekelik region rather than that of the Ba- chu region lithostratigraphically.
