Abstract : according to sedimentary characteristics of the carboniferous taiyuan formation in feicheng coal field , including lithology , size distribution , sedimenta ry structure , geochemistry and paleontology etc . , the carboniferous paleoenvironme nt of this area is divided into carbonate open platform and tidal flat environme nt . it is recognized that the taiyuan formation is formed in the epicontinental c oast which is dominated by the tidal . the peat flat is the important paleoenviron ment 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 文摘:根據(jù)肥城煤田石炭系太原組的巖性、粒度分布、沉積構(gòu)造、地球化學及古生物等沉積特征,將該區(qū)晚石炭世古地理劃分為碳酸鹽開闊臺地和潮坪環(huán)境,認為太原組形成于潮汐作用為主的陸表海海岸,泥炭坪是成煤的重要古地理環(huán)境,潮渠對煤層有一定的破壞作用,地殼的脈動性振蕩作用是控制沉積環(huán)境演化和聚煤作用的主要因素。
