| 摘 要： | 祁连县俄博乡土圈沟、大擦汗沟、柯柯里等剖面的粉砂岩、砂质页岩、泥质页岩岩层之中，首次发现丰富的孢粉化石，计39属74种(其中包括1新种)，疑源类8属9种。推出Verrucosisporites(8．6％)-Triadispora(2％)-Trematosphaeridium(7．2％)的孢粉组合。该孢粉组合面貌应归于中三叠世Anisian期。它的发现为该套地层的进一步研究与合理归属提供了最新成果。

| Abstract: | The abundance microfossil flora is discovered in the siltstone shale and mud shale of the sections of Tujuan chimb,Dachahan chimb,Kekeli and so on of Ebo countryside of Qilian county.The fossils have 39 genera 74 species(including one new species) and 8 genera 9 species of Acritarch.It is derived that the sporosollen combination of Verrucosisporites(8.6%)-Triadispora(2%)-Trematosphaeridium(7.2%).The combination due to middle trissic epoch Anisian age.It is best new harvest for more investigating and attaching with reasonal stratum. |
