摘要: 塔里木盆地轮南地区晚奥陶世地层划分和对比目前尚未统一。在介绍桑塔木组的原始含义及其演变的基础上, 根据《中国地层指南及其说明书》关于组的含义及其建组原则, 重新厘定了桑塔木组的含义。同时对轮南地区上奥陶统桑塔木组及轮南晚奥陶世生物地层进行了划分与对比。认为其时代为宝塔期晚期至五峰期。新的划分与对比, 使研究的精确程度, 有了进一步提高.

Abstract: There have not been an unified classification and correlation of Late Ordovician strata in Lunnan area of Tarim basin. This paper pre-sents original meaning and evolution of Sangtamu formation, based on which and principles about formation definition and its classification giv-en by A Guide Book of China's Geologic Positions, redefined the meaning of Sangtamu formation, and makes clasification and correlation of Late Ordovician biostrata in Lunnan area, including Sangtamu formation of Upper Ordovician. Study indicates that the era of Sangtamu forma-tion should be proper in Late Baota epoch to W ufeng epoch, which will be as a new guide for in-depth study of Lunnan 's stratigraphic classfica-tion and correlation.

Key words: Tarim basin, Lunnan area, Upper Ordovician, stratigraphic classification, stratigraphic correlation
