Sporo-pollen assemblages in Yubei area, Tarim Basin and a discussion on its age
-
摘要: 通过对塔里木盆地玉北地区8口钻井324块孢粉样品的分析鉴定数据进行系统整理,在区块内泥盆系-古近系建立了9个孢粉组合。孢粉组合特征表明,产孢粉地层时代为晚泥盆世-渐新世。孢粉组合的建立和时代的讨论使之与精细地层研究工作相适应,为地层划分和时代确定提供了生物地层学依据,从而更好地服务于生产实践。Abstract: The sporo-pollens of the Devonian-Paleogene in Yubei area, the Tarim Basin are divided into 9 assemblages on the basis of 324 samples derived from 8 wells and combining with the latest achievements of stratigraphic research. The sporo-pollen assemblages indicate that the stratigraphic age is from the late Devonian to the early Oligocene. The studies of sporo-pollen assemblage and its age provide a biostratigraphic evidence for stratigraphic division and age determination, and are helpful for field practices.
