The Cretaceous Songliao basin in Northeast China and several strongly inverted, smaller satellite basin remnants east of it represent one of the world largest lacustrine basin system. While the burial and thermal evolution of the Songliao basin is well studied, the development of the eastern area with exhumed basement highs and basin remnants is less understood. Therefore, an integrated evaluation of the thermal history of both the basement highs and the basin remnants has been performed using low-T thermochronology and burial/thermal modelling based on vitrinite reflectance data, respectively.
Herein, we demonstrate an integrated approach of gravity interpretation and modelling to refine an existing geological 3D SKUA-GOCAD model in the south of the North German Basin (Saxony-Anhalt/Brandenburg cross-border region).
