Long-wavelength effect of mantle flow within the Basin and Range Province. a Map of ratio of TGPE/TBCS at 9 Ma. Blue vectors are velocity field estimates relative to North America associated with GPE. Black vectors are boundary condition velocity field estimates relative to North America; b same as “a” but at present-day. Red line represents reconstructed position of the East Pacific Rise and SAFS. Blue line represents reconstructed position of continental edge. c Deviatoric stresses from lithosphere coupling with global mantle flow S40RTS46. d Boundary condition solution of deviatoric stresses at present-day (comparison of the compressional directions and magnitudes in both models within the Basin and Range Province emphasizes the long-wavelength effect of mantle flow)
