| 摘 要： | 吉林中部的鹿圈屯组自建组以来， 一直被归入到“下石炭统”。在磐石明城附近鹿圈屯组上部的4个样品中发现的牙形刺化石，以Idiognathoides corrugatus , Id. lanei，Id. sinuatus，Id. sulcatus，Idiognathodus sinuosus等晚石炭亚纪（宾夕法尼亚亚纪）巴什基尔期典型分子为特征，表明鹿圈屯组上部存在晚石炭亚纪早期的沉积。其中Idiognathodus和Streptognathodus较为原始分子的出现，表明鹿圈屯组上部的时代与巴什基尔期的中、晚期相当。

| Abstract: | The Lujuantun Formation has been listed as “Lower Carboniferous” since its founding. Some conodonts are found in four samples from the upper part of Lujuantun Formation in Mingcheng，Panshi area, Jilin Province. Among them, Idiognathoides corrugatus, Id. lanei, Id. sinuatus, Id. sulcatus, Idiognathodus sinuosus are representative species of the Early Pennylvanian. Moreover, the fact that both Idiognathodus and Streptognathodus originally appear indicates that the age of the upper part of the Lujuantun Formation approximately corresponds to the middle-late Bashkirian. |
