龙永煤田童子岩组一段沉积特征与聚煤规律

Sedimentary Characteristics and Coal Accumulating Regularities of the First Member, Tongziyan Formation, Longyong Coalfield

从砂岩体的微观特征、岩性相及沉积组合、相的空间配置等方面,重点分析研究含煤段的沉积特征与聚煤规律。提出了滨海碎屑沉积体系、潮坪沉积体系、障壁岛—泻湖沉积体系和浅海沉积体系为童子岩组一段的沉积环境,并阐述了聚煤规律。

From aspects of microscopic features of sandstone bodies, lithofacies and sedimentary association, spatial configuration of facies,the paper put analysis and research emphases on coal-bearing strata sedimentary characteristics and coal accumulating regularities. Put forward an opinion on depositional environment of Tongziyan formation is of littoral clastic, tidal flat, barrier island-lagoon and shallow sea depositional systems, and set forth coal accumulating regularity as well.
