摘要
在野外剖面观察与岩心柱状分析基础之上,综合岩性、沉积构造、古生物及地球化学标志,本文分析了古交矿区晋祠组和太原组沉积环境,划分出主要包括陆表海碳酸岩台地沉积体系、泻湖-潮坪沉积体系和三角洲沉积体系三种沉积体系。结合华北晚古生代总体聚煤特征及已有成煤模式,认为本区主要为浅水三角洲成煤模式。
Based on observation of outcrop and analysis of columnar core, and integrated with lithological characters, sedimentary structure, paleontology and geochemical symbols, the paper analyzes the sedimentary environment of Jinci formation and Taiyuan formation of Gujiao mine. Three depositional systems are classified： epicontinental sea carbonate platform, lagoon-tidal flat, and delta depositional systems. Combined with the North China late paleozoic coal-accumulation features and coal formation model, the author concludes that the area is dominated by shallow water delta depositional model.
