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－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。 Based on the sedimentary characteristics (lithology, structure, sedimentary structure, paleocurrent characteristics, plane-section and geometry in the three-dimensional space) of the sandstone (body) in the bridgehead of the Taiyuan Formation and the erosion pattern and uplift of the underlying m13 thick coal seam Covering the unique control of m11 coal accumulation, it is considered to be a product of a special transitional type of river environment and the paleotectonic background of the same depositional period is further analyzed.
