| 摘 要： | 松辽盆地南部沙河子组自下而上划分为2个孢粉组合.1）克拉梭粉（Classopollis）-拟云杉粉（Piceites）-紫箕孢（Osmundacidites）组合，分布于沙河子组一段.2）三角粒面孢（Granulatisporites）-三角瘤面孢（Lophotriletes）-无突肋纹孢（Cicatricosisporites）组合，分布于沙河子组二段.上述孢粉组合研究证明，沙河子组一段的地质时代为早白垩世凡兰吟期（Valanginian），沙河子组二段的地质时代为欧特里沃期（Hauterivian）.

| Abstract: | Form bottom to top,the Shahezi Formation in the Southern Songliao Basin can be divided into two sporopollen assemblages,i.e.the Classopollis-Piceites-Osmundacidites assemblage and the Granulatisporites-LophotriletesCicatricosisporites assemblage.The former is distributed in the first member of the Shahezi Formation; while the latter,in the second member.Study on the sporopollen assemblages demonstrates that the first member of Shahezi Formation geochronologically belongs to the Valanginian Age of Early Cretaceous Epoch; while the second member,Hauterivian Age. |
