Cretaceous paleogeography and paleoclimate and the setting of SKI borehole sites in Songliao Basin, northeast China

► We analyze the Cretaceous paleogeography and paleoclimate in the Songliao Basin. ► The basin located in the Northern Hemisphere middle latitude spans up to 85-90 m.y. ► Tectonic activity and water supply controlled the character of sediment facies. ► The climate of the basin was temperate and humid with relatively abundant rainfall. ► There were four cooling, three warming and three semiarid events in the Cretaceous.
