Objectives: The Neoproterozoic is a very interesting geological period with significant climatic changes. The extent, duration and number of Neoproterozoic glaciations are still debated. Glacial deposits of the North China Craton (NCC) are poorly studied, but offer excellent exposures of Neoproterozoic age, which can shed light on glacial events, in particular, the Fengtai Formation in the southeastern margin of the North China Craton. Methods:The Fengtai Formation is only defined in the southeastern margin of the North China Craton (NCC), and two main measured sections were studied in the Wanbei and Wanxi areas. Stratigraphic sections were measured through the formation in each region. The characteristics of individual facies and their interpretation origin were presented, together with the spatial distribution of facies associations. The samples were collected from surface outcrop across a range of facies in the Fengtai Formation, while avoiding highly weathered or altered samples. Polished thin sections were selected from the samples and prepared for petrographic analysis by polarization microscope. Results: The tectonic setting of the southeastern margin of the North China Craton was a steep- rimmed carbonate platform, and the Fengtai Formation developed in the continental margin. Different from typical complex composition diamictites, both the gravels and matrix of the Fengtai Formation diamictites are carbonates which originate from the underlying carbonate strata. Conclusions: The glaciations only affected the continental margin, and diamictites of the Fengtai Formation resulted from gravity flow and glacial movement. The development of the Fengtai Formation develops in the Ediacaran and hosts several glacial—interglacial depositional cycles. Correlated with the Luanquan Formation in the southern margin and Zhengmuguan Formation in the western margin, clarified the evolutionary history of the NCC during Neoproterozoic glacial—interglacial.
