| 摘 要： | 峨眉山早二叠世地层发育,化石丰富,含大量苔藓虫化石。栖霞组以Fenestella sp.(A)为特征,茅口组下部以Araxopora hayasakai最丰富,上部则以Meekopora emeishanensis(sp.nov.)为特色。Meekopora属在我国过去仅发现于石炭系,现该属首次在蛾眉山下二叠统中发现,其层位大致相当子北美早二叠世的瓜达卢普组(Guadalupian)。

| Abstract: | In Emei Mountain area lower Permian strata are well developed and fossiliferous. Bryozoa is abundant in particular. Qixia Formation is characterized by Fenestella sp. (A), Araxopora only appears in Misellina zone or Parafusulina zone. The first and second members of Maokou Formation containabundant Aroxopora hayasakai, and can be correlated with Neoschwagerina zone. The third and fourth members of Maokou Formation contain Meekopora emeishanensis (sp. nov.), and may be correlated with Yobeina zone.In China,Meekopora was previously known only in Carboniferous System. Now it is firstly found in Lower Permian in Emei Mountain, which is approximately correlated with Guadalupian of North America. |
