摘　　要：本文介绍了两淮地区太原组的岩性特征、化石组合及与上覆或下伏地层间的接触关系。根据蜒类和牙形石组合特征的研究,确认本区太原组可能只相当于庙沟石灰岩至东大窑石灰岩的层位(见表1),其时代应属晚石炭世中、晚期。此外,详细讨论了太原组蜒类的生境。Presentation is given of the lithological characteristics, fossil assemblages and overlying-underlying contact modes of the Taiyuan Formation in Huainan-Huaibei area. It is confirmed by researches on features of fusulinid and conodont assemblages that the Taiyuan Formation in this area Js at most correspondent to the horizon ranging from the Miaogou limestone to the Dongdayao limesione, belonging to the middle-late Late Carboniferous Epoch
