| 摘 要： | 串岭沟组常以页岩为其主要岩性组合。兴隆地区串岭沟组据岩性、岩相组合、垂直相序及厚度变化可划分为3个区：西北区、过渡区和东南区，其中西北区岩性组合为泥岩夹薄层细砂岩，厚49－62m；过渡区为泥岩、细砂岩夹两套厚60－240m不等中粗粒砂岩，厚度达600m；东南区以泥页岩为主，厚度大于530m。它们在横向上呈指状交错关系，其沉积环境隶属于小潮海岸型障壁岛－泻湖沉积体系。

| Abstract: | The lithologic association of the Chuan linggou Formation consists mainly of shales.Ac cording to the lithology and lithofa cies association,vertical facies sequence and change in thickness,three areas may be dis tinguished:the northwest area,transitional area and southeast area.The lithologic association of the northwest area is com posed main ly of mudstone with thin-bedded fine sandstone,49-62m thick;that of the transitional area,mudstone and fine sandstone with two beds of medium-to coarse-grained sandstone vary ing in thickness from60to240m,with a total thickness of600m;that of the southeast area,mainly mudstone-shale,>530m thick.Laterally they interfinger each other and their sedimentary environment be-longs to the barrier island-la goon system of mi crotidal coastal type(tidal range0-2m). |
