The distribution and sedimentary characteristics of the Nanhua glacial strata in China have always been the focus of the Neoproterozoic study, and whether there is glacial strata of Nanhua System(Cryogenian System) in northern China has always been controversial. In this paper, the field geological survey, comparison and study of Neoproterozoic lithostratigraphic units in Liaoning region are conducted in the past three years, it is determined that moraine deposits existed in the Neoproterozoic period in the northern Liaoning area, and two stages of moraine action have been divided, namely, the Neoproterozoic Nanhua Yintun Ice Period and the Neoproterozoic Nanhua Fanhe Ice Period. The first glacial period is a set of continental moraine accumulation, whose main lithology is grayish- purple thick massive conglomerate intercalated with gravelly coarse sandstone lens, distributed near Tieling in the northern Liaoning. The second glacial deposition consists of the northern Liaoning, mainly involving the Fanhe Formation of continental ice water accumulation. At the same time, it is confirmed that the Yongning Formation (terrigenous river facies) was formed before the first Yintun glacial period; the Chenqianhu Formation (continental facies ) were formed in the interglacial period between the first Yintun glacial period and the second Fanhe glacial period.
