四川冕寧沙壩麻粒巖的巖石地球化學性質及形成時代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
根據肥城煤田石炭系太原組的巖性、粒度分佈、沉積構造、地球化學及古生物等沉積特徵,將該區晚石炭世古地理劃分為碳酸鹽開闊臺地和潮坪環境,認為太原組形成於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境演化和聚煤作用的主要因素。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
