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，时代为早白垩世阿普第期 The Shiywu Formation of the Shiwu Fault Depression is well developed with stable distribution, top and bottom boundary, lithological characteristics, sedimentary cycles and thick clear spore-rich fossils with the conditions of formation. The establishment of the Shiwu Formation will certainly contribute to the deep stratigraphic division and contrast in Songliao area. The Classopollis-Cyathidites-Tricolpopollenites from the Shiwu Formation can be compared with the Guantou Formation and Gecun Formation in the south of China in the era of Early Cretaceous Apus Period
