Petrogenesis of late Mesozoic granitoids in southern Jilin province, northeastern China: Geochronological, geochemical, and Sr-Nd-Pb isotopic evidence

► The Mesozoic granitoids are studied in the southern Jilin province, NE China. ► The high Mg# granitoids formed via magma mixing. ► The low Mg# granitoids were derived from partial melting of the lower crust. ► Spatial variations of their compositions reveal heterogeneity of the crust.
