摘　　要：据对位于天山南麓、塔里木盆地西北缘新疆乌尊布拉克剖面■类化石的研究,建立5个化石组合带,由下而上依次为Beedeina-Fusulinella组合带、Rauserites postarcticus-Quasifusulina paracompacta组合带、Prae-pseudofusulina-Carbonoschwagerina-Bosbytauella组合带、Praepseudofusulina-Sphaeroschwagerina组合带和Eoparafusulina组合带,地层时代从石炭系莫斯科期晚期至早二叠世亚丁斯克期,表明乌尊布拉克地区从石炭系莫斯科期晚期开始接受海相沉积,以碳酸盐台地边缘相的生物碎屑灰岩为主,不整合超覆于下部的泥盆系之上。类组合带在横向上可以与华南、俄罗斯地台的■带相对比,在组合面貌上更接近于伊朗北部Alborz山脉Emarat组的■类化石组合。The Wuzunbulake Section is located at the southern foot of Tianshan in the northwestern region of the Tarim Basin.Carbonate successions from Upper Carboniferous to Lower Permian are deposited unconformably on Devonian clastic rocks.Five fusuline assemblages were recognized,ranging from Late Moscovian（Late Carboniferous） to Artinskian（Early Permian）.They are the Beedeina-Fusulinella Assemblage,Rauserites post-arcticus-Quasifusulina paracompacta Assemblage,Praepseudofusulina-Carbonoschwagerina-Bosbytauella Assemblage,Praepseudofusulina-Sphae-roschwagerina Assemblage and Eoparafusulina Assemblage in ascending order.These fusuline assemblages can be correlated with those from South China and the Russian Platform.Their general appearance is most similar to those of the Ermarat Formation from the Alborz Mountains of Iran.
