Abstract

Late Cretaceous Yaojia-Nengjiang Formation in Songliao Basin is a set of sedimentary formation with the integrated base level rising and falling. The oil shale, formed during the maximum flooding surface period at the bottom of K2n2, distributed steadily in the whole basin. The oil shale was not only the standard interface for sequence and stratigraphic correlation, but also an important source rock and cap rock. K2y and K2n1 are large-scale lacustrine and retrograded delta sediment formed in lacustrine transgression period. Sediments of K2n2 and K2n5 were large-scale lacustrine and procreation delta sediment formed in forced lacustrine regression period. Gravity flow channel and terminal turbidity fan were developed in the major axis direction of the material source during the lacustrine transgression period of K2n1. Large-scale slump fan sediment was developed in front of the procreation delta during the forced lacustrine transgression period of K2n2.
