SW U.S. plate tectonic reconstruction for (A) middle Jurassic, (B) Early Cretaceous, (C) Late Cretaceous, (D) Latest Cretaceous, (E) late Cenozoic, and (F) Recent time (modified after DeCelles, 2004; Saleeby and Dunne, 2015). Farallon/Pacific plate trajectories from Engebretsen et al. (1985). Surface outline of lowermost crust and upper subcontinental mantle lithosphere (LC-SCML) foundering from Levander et al. (2011) and Erdman et al. (2016). Core complex and schist kinematics from Dickinson (2009) and Chapman (2017), respectively. See text for details. CC—Camp Creek; CV—Chino Valley; MTJ—Mendocino triple junction; POR—Pelona-Orocopia-Rand schist; RTJ—Rivera triple junction; SC—San Carlos; Gdl—Guadalupe plate.
