Abstract During the investigation of Mesoproterozoic Changchengian and Jixianian lithostratigraphic units occurred in Xiajiagou area of western Liaoning Province, the moraine conglomerate terrane of Yintun Formation of Lower North Nanhuan System, Neoproterozoic, is found above the Chuanlinggou Formation of Mesoproterozoic Changchengian System. The two show an angular unconformity contact relation. The discovery fills a gap in the Neoproterozoic continental lithostratigraphic unit deposition and adds new content to the discussion of Neoproterozoic crustal evolution history in western Liaoning, which has great geological implication.
