| 摘 要： | 大红峪组为燕山地区惟一中、新元古界碎屑岩与碳酸盐岩混合沉积地层。根据“岩性—岩相—相序”的研究思路与方法 ,在详细研究成因单元基础之上 ,将大红峪组地层叠置规律归纳为碎屑岩型、混合岩型、碳酸盐岩型三种相序 ,横向上划分为两个相区 :东部相区以碎屑岩为主、西部相区以碳酸盐岩为主 ,沉积环境表现为由东部靠近陆源区缓斜坡砂质海滩向西部过渡为浅水碳酸盐台地型相模式 ,沉积作用以潮汐作用为主 ,偶见浅水风暴沉积

| Abstract: | The Middle Proterozoic Dahongyu Formation is solely compound sedimentary stratigraphy of Middle to Upper Proterozoic age in the Yanshan region, which is composed of terrestrial rocks and carbo- natite. Based on lithology, lithofacies, succession, as well as genetic units, the Dahongyu Formation is divided into three types:terrestrial rocks, mixing rocks,and carbonatite,and the study area is divided into the eastern part which is composed of terrestrial rocks,and the western part which is composed of carbonatite. Sedimentary environment of the Dahongyu Formation is interpreted as ramp-platform model near terrestrial provenance, which records a tidal-dominated and shallow hurricane sedimentary environment. |
