Abstract: The Yangling psephyte is distributed in the Chongyi-Dayu area, southwestern Jiangxi province.Using the latest research data the authors describe the stratigraphic sequences,lithology,sedimentary structures and fossils of three measured sections of the Yangling psephyte.According to the contact relationships of the Yangling psephyte with its overlying and underlying strata,microfloras and composition and sources of gravels,it is considered that the age of the Yangling psephyte should be Silurian.From an analysis of the tectonic setting,the area is located in the junction between the South China and Yangtze plates,indicating that the Yangling psephyte is a sequence of molasse-facies deposits in the Caledonian orogenic belt.
