This paper deals with the coal-bearing measures of the Taiyuan Formation (C2) in the Fugu - Baode mine of the Hedong coalfield (the Northwest China) on the basis of the sedimentary characteristics of a main sandstone body (the Qiaotou sandstone body), including its mineralogy, petrology, textures, sedimentary structures, paleocurrents and spatial geometry. The depositional environment of the Qiaotou sandstone body and its erosional pattern in the m13 coal-seam and its spatial relationship to the overlying m11 coal-seam (above) were determined. The results suggest that the sandstone body was a product of a fluvial environment of a special transitional type.
