| 摘 要： | 根据太原组桥头砂岩（体）的沉积特征（岩性、结构、沉积构造、古流特征、平面一剖面及三维空间上的几何形态）以及该砂体对下伏ｍ１３厚煤层的冲刷样式和对上覆ｍ１１煤聚集的独特控制方式，认为它属一种特殊过渡类型的河流环境的产物，并进一步分析了同沉积期的古构造背景。

| Abstract: | This present paper deal with the data about Taiyuan Formation(C3)coal-bearing measures of Baode mining in Hedong coalfield (NW of China),based on,in the concrete, sedimentary characteristics of Qiaotau sandstone body (lithology,textures,sedimentary structures,paleocurrents and spatial geometry).And finally,the depositional environment of Qiaotau sandstone body and its erosional pattern on m13 coal-seam (underlying).its special controlling m11 coal-seam(above)has been determined. Equally, all analysis results was emphasized the synsedimentary tectono-geodynamic setting. |
