The article analyses the feature of deeply seismic reflection and deeply layer-loop structure, based on deeply seismic data. Applying the theory of asymmetry extension, we research the deeply layer-ring structure, tectonic feature of basement, tectonic framework of Jurassic faulted depression, and authors establish the genetic model of northern Songliao basin. At last, authors think the slip-detachment fault of basement is the most important factor controlling the development of Jurassic faulted depression.
