| 摘 要： | 本文试图根据孢粉组合中各类别成分的分析,推断盆地从始新世至渐新世的古植被、古气候有三个不同发展阶段。依据化石生物群中不同类别的特征和含量分析、以及孢粉与藻类的比值,推测早第三纪盆地属大陆滨海区陆相湖泊。

| Abstract: | Based on the analysis of the sporo-pollen composition, an attempt is made in this paper to infer that the basin has undergone three developmental stages of paleovegetation and paleoclimate from Eocene to Oligocene. According to the characters and contents of different groups in the fossil biota and the sporo-pollen to algae ratio, it might be inferred that the paleogene basin was an ancient lake on coastal plain. |
