Abstract:
By means of systematic sample along the Guanjiagou Formation section in Wenxian County, Gansu Province, many Micropalaeoflora fossils are collected, and identified as 16 genera and 28 species. According to the fossil assemblages of Nanhua System and Sinian in South China and other areas, the characteristics of fossil assemblages in Guanjiagou Formation section are compared with that of Nantuo Period of Later Nanhua stage in the eastern of Three Gorges and the northwest of Sichuan, and the age of Guanjiagou Formation should belong to Nantuo Period of Later Nanhua stage. The result is significant to study the geological age and stratigraphic subdivision in Guanjiagou Formation.
