| 摘 要： | <正> 十屋组在松辽盆地南部十屋断陷十分发育,分布稳定,界线清楚,含丰富的孢粉化石,岩性特征、沉积旋迴、厚度清楚。 建立十屋组是为了澄清松辽盆地深层“登娄库组”对比混乱局面,建立正确地层层序,以利于区域地层对比。由于登娄库构造远离松基六井,南北相差近180km,将松基六井

The Shiwu Formation in the southern Songliao Basin and the characters of its sporo-pollen assemblage |
| |
| Abstract: | The Shiwu Formation, consisting of terrigenous clastic rocks of up to 2500m thick, is widely distributed in the Shiwu fault depression in the southern part of the Songliao Basin with a distributive area of about 1600km2. This formation yields sporo-pollens fossils characterized by an abundance of Classopollis or Cyathidites, which constitutes Classofollis-Cyathidites-Tricolpopollenites Assemblage, and may be correlated with the Guantou Formation in western Zhejiang, Lingxiang Group in Hubei, Dongjing Formation in Hunan, Gecun Formation in Jiangsu and Tonohata Formation in Northeast Japan. It is regarded to be of Aptian age (Middle Cretaceous). |
