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
