摘　　要：以沉积学为研究手段,通过对野外露头剖面宏观岩石学特征、沉积构造特征的详细研究,结合大量室内薄片的微观岩石学特征,以及地球化学分析资料,认为燕山地区1.6～1.0Ga(高于庄组—景儿峪组)主要有海相碳酸盐岩和海相碎屑岩2种沉积体系,海相碳酸盐岩沉积体系可划分为碳酸盐岩台地和生物礁2个相,以及3个亚相和5个微相;海相碎屑岩沉积体系可划分为浅海陆棚和无障壁型海岸2个相,以及4个亚相。其中,碳酸盐岩沉积体系主要发育在研究区高于庄组、雾迷山组、杨庄组、洪水庄组、铁岭组和景儿峪组;碎屑岩沉积体系主要发育在下马岭组和长龙山组。最后,总结出了该地区的沉积相模式图。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. Marine carbonate sedimentary system are composed of two facies which are carbonate platform facies and reef facies, three subfacies and five micro-facies; marine clastic rock sedimentary system are composed of four subfacies and two facies which are neritic shelf facies and no-barrier coast facies. Marine carbonate sedimentary system are mostly developed in Gaoyuzhuang Formation, Wumishan Formation, Yangzhuang Formation, Hongshuizhuang Formation, Tieling Formation and Jingeryu Formation; marine clastic rock sedimentary system are mostly developed in Xiamaling Formation and Changlongshan Formation. Finally, the sedimentary facies models in Yanshan Area are summarized.
