摘要
十屋断陷十屋组十分发育,分布稳定,顶底界线、岩性特征、沉积旋回和厚度清楚,含丰富的孢粉化石,具备建组条件。十屋组的建立必将有助于松辽地区深部地层划分对比。十屋组产Classopollis-Cyathidites-Tricolpopollenites孢粉组合,可与我国南方馆头组、葛村组对比。
The Shiwu Formation in Shiwu half-graben developed well and widely spread. In well-SN 10 near Shiwu township in Gongzhuling City, its sequence is complete and the boundaries of top and bottom are clear, and its lithological character, sporopollen assemblage and thickness are distinct, thus the stratum is named Shiwu Formation. The sporopollen assemblage of the formation is characterized by abundant Classopollis, Cyathidites and a few Tricolpopollenites, Clavatipollenites etc. Therefore, it is called as Classopollis-Cyathidites- Thicolpopollenites assemblage, which could compare with that of the Guantao and Gecun Formations in South China. Its age should belong to Aptian of Early Cretaceous.
