龙永煤田坑柄井田南区沉积相研究

Research on Sedimentary Facies in Kenbing Mining Field South Area, Longyong Coalfield

沉积相研究是揭示古泥炭沼泽形成的重要标志,而古泥炭沼泽是聚煤的主要场所,是恢复含煤地层沉积过程的重要环节。通过对龙永煤田坑柄井田南区地质资料的分析,从岩矿特征、粒度特征、层理特征、古生物特征等方面对沉积相及其古泥炭沼泽的发育演化过程进行研究,划分了三种沉积相类型并在此基础上分析其发展演化模式。

Researches on sedimentary facies can disclose the formation of ancient peat swamps, where most coal deposits are found. Through geological data analysis on Kengbing Mining Field South Area, Longyan Coalfield, the authors carry out study on sedimentary facies and the evolution of ancient peat swamps from aspects of ore characteristics, granularity characteristics, bedding characteristics and obtain three categories of sedimentary facies and then analyze their development evolution patterns.
