| 摘 要： | 在对四川西部巴塘县波格西地区晚古生代地层剖面研究的基础上，从岩性、岩相分析入手，将该区地层划分为６个组级岩石地层单位。根据所含化石确定地层形成时代为泥盆纪至二叠纪。在与邻区岩石地层对比基础上，将木里小区前人已建立的崖子沟组延入本区，修订了波格西组和龙巴组含义，新建了那来组、夺给组和帮相组，选定了剖面层型。从而完善了稻城小区晚古生代岩石地层系统。

| Abstract: | On the basis of a detailed study of the Late Paleozoic section in the Bogexi area, Batang county, western Sichuan, six lithostratigraphic formations may be recognized in the study area. According to the conodont and fusulinid fossils, their ages are determined to be Devonian Permian. The stratigraphic sequences in the area are successively (in ascending order) as follows: the Yazigou Formation , which uses the name of the Muli district; the Bogexi Formation and Longba Formation ,whose connotations have been revised; the Duogei Formation and Duogei Formation , which is newly established. The Late Paleozoic lithostratigraphic system in the Taocheng has been preliminarily set up and perfected. |
