摘要:

对公婆泉盆地钻孔5005的7块样品分析表明,其孢粉组合是单脊周囊孢阿里粉单肋联囊粉,为三叠系中常见分子,因此认为将其归属为上三叠统为妥。

关键词: 钻孔5005, 孢粉组合, 上三叠统

Abstract:

Based on the analysis of the samples from drill hole 5005,we discovred an sporo-pollen assemblege of Aratrisporites,Alisporites and Colpectopollis.Similar assemblege of fern and pollen can be found in corresponding group,such as Huangshanjie Group in Junggar Basin,Tuha Basin and Shantanghu Basin,Yanchang Group in Ordos Basin,Yangcaogou Group in Liaoxi.These members could often be found in Triassic System.It is suggested that the formation should belong to Upper Triassic.
