This paper analyses the features of field geology, fossil assemblage,petrology of the initial Shixi Formation and the related strata in the YanshanShangrao area, Jiangxi. The fact that the lower part of the initial Shixi Formation actually belongs to the lower part of Zhoujiadian Formation and the middle and upper parts of the initial Shixi Formation actually belongs to the initial Ehulin Formation is new proved. Based on the features of volcanic factes, volcanic cycle analysis and the initial implication of the Shixi Formation, the upper part of the initial Shixi Formation or the initial Ehulin Formation should belong to the Shixi Formation.
