摘要
根据肥城煤田石炭系太原组的岩性、粒度分布、沉积构造、地球化学及古生物等沉积特征 ,将该区晚石炭世古地理划分为碳酸盐开阔台地和潮坪环境 ,认为太原组形成于潮汐作用为主的陆表海海岸 ,泥炭坪是成煤的重要古地理环境 ,潮渠对煤层有一定的破坏作用 ,地壳的脉动性振荡作用是控制沉积环境演化和聚煤作用的主要因素。
According to sedimentary characteristics of the Carboniferous Taiyuan formation in Feicheng coal field,including lithology,size distribution,sedimentary structure,geochemistry and paleontology etc.,the Carboniferous paleoenvironment of this area is divided into carbonate open platform and tidal flat environment.It is recognized that the Taiyuan formation is formed in the epicontinental coast which is dominated by the tidal.The peat flat is the important paleoenvironment for coal accumulation.The tidal channel destroys the coal bed.The pulsative vibration of the crust is the major factor which controls the evolution of the sedimentary environment and the coal accumulation.
