| 摘 要： | 黑龙江孙吴—嘉荫盆地内两口地质探井获得的135块孢粉样品中含有孢粉化石87属,这些孢粉化石可以划分为4个孢粉组合,根据组合特征,这4个孢粉组合的地质时代分别为早白垩世凡兰吟期—欧特里沃期、阿尔必期,晚白垩世桑顿期—坎潘期、马斯特里赫特期,同时含这些孢粉化石的相关的白垩纪地层可以相应划分为下白垩统宁远村组、淘淇河组、上白垩统太平林场组和富饶组。这一研究为重新认识和建立孙吴—嘉荫盆地的地层层序提供重要的古生物依据。

| Abstract: | Sunwu-Jiayin Basin of Heilongjiang Province is a large continental basin with oil and gas resource potential. Based on the analyses and research of 135 sporo-pollen samples from two geological wells in the basin, 87 genera of spores and pollen grains are identified, and four sporo-pollen assemblages are grouped in this paper. According to the characters of the sporo-pollen assemblages, geological ages and the stratigraphic classification and correlation are detailedly discussed. This research provided on important paleontologic evidences to re-recognize and establish the stratigraphic sequence in the Sunwu-Jiayin Basin. |
