摘要
Taking sedimentology as the study means, through overall study on surface macroscopic outcropping characteristics and sedimentary structure, and combining with the micropetrological structure features of laboratorial slice and the element geochemical analysis data, this paper points out that the 1.6~1.0 Ga (from Gaoyuzhuang Formation to Jingeryu Formation) consists of marine carbonate and marine clastic rock sedimentary system among platforms in Yanshan Area. Finally, the sedimentary facies models in Yanshan Area are summarized.
