| 摘 要： | 共测制了13条新疆塔时木塔克拉玛干沙漠中部和北部井下的奥陶系剖面，并在不同的相区发现了不同的牙形刺序列。在北部地区牙形刺带由上而下为：Aphelognathus pyramidalis,Yaoxianognathus yaoxianensis-Belodi-na confluens,Baltoniodus alobatus,Pygodus anserinus,P.serra,Paroistodus proteus,Glyptoconus quadraplicatus和Rossodus manitouensis-Cordylodus rotundatus等带；在中部区，牙形刺带由上而下为：Serratognathus diver-sus,Chosonodina和Rossodus manitouensis-Cordylodus rotundatus等带，另外，本文也讨论了牙形刺带的对比，生物相及本区的古地理轮廓变化，描述了新种Pygodus xinjiangensis。

| Abstract: | Thirteen drilling sections from the northern and central parts of the Taklimakan Desert in the Tarim Basin, Xinjiang have been measured and different conodont zonations in different facies are recognized. In descending order they are : Aphelognathus pyramidalis, Yaoxianognathus yaoxianensis Belodina confluens, Baltoniodus alobatus, Pygodus anserinus,P.serra, Paroistodus proteus,Glyptoconus quadraplicatus and Rossodus manitouensis Cordylodus rotundatus zones in the northern part, and Serratognathus diversus,Chosonodina and Rossodus manitouensis Cordylodus rotundatus zones in the central part. The conodont zonal correlation, biofacies and paleogeographic outline are also discussed and a new species Pygodus xinjiangensis is described here. |
