Late-Miocene thrust fault-related folding in the northern Tibetan Plateau: Insight from paleomagnetic and structural analyses of the Kumkol basin

•The southern Baiquanhe section in the Kumkol basin, northern Tibetan Plateau, spans a time interval of 8.2–4.2 Ma.•Well-preserved growth strata date to 7.5 Ma.•A pulsed basinward deformation was identified in the northern Tibetan Plateau during the late Miocene.
