摘 要: 沉积相研究是进行沉积盆地勘探、评价的一项重要的基础工作。本文根据太平山南北坡实测剖面和薄片研究资料,分析了晚古生代石炭—二叠系各层组的岩性特征、沉积相类型、垂向沉积演化特征。该区主要为几套变质砂岩—板岩组成的暗色碎屑岩系,原岩为几套砂岩、粉砂岩和炭质泥岩,从下往上依次为滨浅海—三角洲—河流相沉积,其亚相和微相类型有障壁海岸体系的泻湖相、潮坪相;三角洲平原分流河道相、天然堤、分流河道间;平原区河流河床滞留沉积、天然堤、河漫滩以及辨状河中的河床滞留沉积、心滩、泛滥平原等。
关 键 词: 石油和天然气能;岩性组合;沉积相;晚古生代;周口店

Abstract: The research of sedimentary facies is an important foundational work for the exploration and evaluation of sedimentary basins. According to data obtained from measured sections in Taipingshan area and research of slices, the lithological features, the types of sedimentary,vertical deposition evolution sedimentary characteristics of the Late Palaeozoic Carboniferous~Permian Stratigraphy are analyzed in this paper. These formations consists of several sets of metamorphic sandstone-slate dark clastic rock series, which original rock are several sets of sandstones, siltstones and Carbonaceous mudstones, which belongs to seashore-delta-river deposition upwards. Their subfacies and microfacies types have the characteristics of lagoon and tidal flat facies under barrier island system; the characteristics of distributary channel, levee and interdistributary under delta plain; the characteristics of lag deposits, natural levee, and overbank floodplain under river and the characteristics of lag deposits, channel bar and floodplain under braided river.
Key words: petroleum and natural gas energy; lithofacies assemblages; sedimentary facies; late Palaeozoic; Zhoukoudian
