| 摘 要： | 西藏申扎地区奥陶系地层组的建立不是根据岩性特征，而是根据地层中的化石组合和多重地层划分的原则。笔者认为，申扎组应被废弃，德悟卡下组底界应作修订，并对该地区奥陶系岩石地层单位进行了简要的时代讨论和对比。

| Abstract: | Some formations of Ordovician were established based on fossil assemblages rather than lithology. According to the principles of the multiple stratigraphic division, the authors in this study contend that the Xainza Formation should be abolished, and the basal boundary of the Dewukaxia Formation should be redefined. Finally the stratigraphic ages and correlation of the Ordovician lithostratigraphic units in the study area are discussed. |
