Abstract
The term formation is the basic lithostratic unit which is divided based on the lithological characters. The Carboniferous Permian strata developed well in the Deriangma Xiala section and the Angjie section in Shenzha, Tibet. All the lithostratic units of the Carboniferous and Permian strata in this area were named after them. However, some of them were not defined based on the lithological characters but on the fossil assemblages in the sections, and do not accord with the principle of the multiple stratigraphical classification. And the lithostratic system of the Carboniferous Permian has been a controversial subject for a long time. The lithostratic systems of the Carboniferous Permian in the area are manily remarked by the author in the present paper, and the Carboniferous Permian boundary is discussed briefly.
