The sedimentary facies of Mesoproterozoic in Yanshan aulocogen is regarded as coastal to shallow sea region for a long time. Based on survey in north Hebei province, a lots of abysmal and subabysmal deposit of Mesoproterozoic in Yanshan aulocogen, such as siliceous shale, Mnbearing shale, turbidite, solving nodular limestone deposited under calcium carbonate compensation depth and so on, are founded in Tuanshanzi Formation, Gaoyuzhuang Formation, Yangzhuang Formation, Wumishan Formation, Hongshuizhuang Formation, and Tieling Formation. It is important for understanding of the evolution of Yanshan aulocogen.
