Objective The Jilin-Liaoning area has widely spread Meso-and Neoproterozoic sediments and is always a focused area for researching Precambrian geology.Previous study has achieved a series of results about Neoproterozoic stratigraphy in this area,but the lack of precise geochronological data and signs of stratigraphic correlation has resulted in the long controversial stratigraphic age and regional correlation.During recent years,we have conducted large amounts of stratigraphic and sedimentary research about the Neoproterozoic strata

Previous study has achieved a series of results about Neoproterozoic stratigraphy in this area, but the lack of precise geochronological data and signs of stratigraphic correlation has resulted in the long controversial stratigraphic age and regional correlation. Working recent years, we have conducted large amounts of stratigraphic and sedimentary research about the Neoproterozoic strata
