淮南含煤区上古生界沉积环境演化研究

Research on evolution of Upper Paleozoic sedimentary environment in Huainan coal bearing area

运用煤地质学、沉积学方法研究了淮南含煤区石炭-二叠系的主要岩石类型及岩性特征,分析了矿区上古生界的沉积环境,厘定出了淮南含煤区晚古生代地层发育的四类沉积体系:碳酸盐台地沉积体系、障壁—潟湖—潮坪沉积体系、浅水三角洲沉积体系,以及河流—湖泊沉积体系;探讨了南华北盆地淮南含煤区晚古生代的岩相古地理特征及盆地演化序列,并分析了该区的沉积相和沉积模式。

This paper studied the main rock types and the lithologic characteristics of the Carboniferous- Permian coal bearing area of Huainan by using the coal geology, sedimentology, analyzed the sedimentary environment of the mining area of Upper Paleozoic, classified the four types of sedimentary system in Huainan coal bearing area of Late Paleozoic strata development： carbonate platform depositional system, barrier-Lagoon-tidal flat sedimentary system, shallow water deltaic depositional system and fluvial-lacustrine depositional system; discussed the basin evolution sequence and the lithofacies palaeogeographic characteristics in the southern North China Basin of Late Paleozoic coal bearing area of Huainan, and analyzed the sedimentary facies and sedimentary model.
