The LA-ICP-MS ages and trace element data were obtained at the Wuhan Sample Solution Analytical Technology Company Limited, Hubei Province and the Key Laboratory of Paleomagnetism and Tectonic Reconstruction of Ministry of Natural Resources, Institute of Geomechanics, Chinese Academy of Geological Sciences (CAGS) in Beijing.The 40Ar/39Ar incremental heating analytical results of 17 hornblende, muscovite and biotite samples (Tables S2 to S18) of the mid- to upper crustal exhumed rocks from a northsouth corridor across the western part of northern North China continental arc and its retroarc foreland basin from Bayan Obo to Baotou. 40Ar/39Ar incremental heating analysis of 15 hornblende, muscovite and biotite samples (Tables S2 to S12, S15 to S17) was performed in Oregon State University (OSU) Argon Geochronology Laboratory, USA. Two muscovite samples (Tables S13, S14) were analyzed at the Laboratory of Isotope Thermochronology, Institute of Geology, CAGS, Beijing.
