From: Craton deformation from flat-slab subduction and rollback
a, Tectonics of basins and mountains in the NCC and adjacent regions21. b, Magnified representation of the Yanshan Mountains24,38. The pink, light blue, light green, yellow, and faint yellow areas represent the Triassic, Jurassic–Earliest Cretaceous, Early Cretaceous, Early and Late Cretaceous, and Cenozoic basins, respectively. The red and green dots represent the locations of U‒Pb zircon-dated volcanic and intrusive rocks, respectively, and the dotted, bright pink line represents the projected baseline. The grey stars and lines indicate wells and sections from which isostatic and flexural backstripping calculation data are available.
