英文摘要	The study of drainage evolution in the Songnen Plain, Northeast China, is essential for understanding the interactions between tectonics-topography-climate-drainage evolution in the region. Despite this, it remains undear whether the paleo-Songhua River (upper-middle reaches of the Songhua River) once flowed westward into the Songnen Plain and what forcings influenced the drainage development of the Songnen Plain. In this contribu- tion, we provide insight into drainage development on the Songnen Plain using an integrated approach of magnetic susceptibility, geochemical (elemental and Sr-Nd isotopic) and heavy mineral composition recovered from a 102-m sediment core sediments extracted from the eastern edge of the Songnen Plain with sedimentological and topographic archives. Our results show that a dramatic provenance shift occurred at the depth of 62.2 m (similar to 0.94 Ma) in the core sediments. It is proposed that the Songhua River was separated by the Jia-Yi (Jiamushi-Yilan) divide into two segments before similar to 0.94 Ma, the west-flowing proto-Songhua River and the east-flowing proto-Sanjiang River (lower reach of the Songhua River). However, the proto-Songhua River reversed direction at similar to 0.94 Ma when the Jia-Yi divide was cut through by headward erosion of the proto-Sanjiang River, marking the birth of the Songhua River as a single, eastward-flowing river system. Tectonics is suggested as the first- order control on the evolution of the Songhua River before 120 Ma, whereas climate changes may be responsible after 1.20 Ma. (C) 2020 Elsevier B.V.
