  • Crustal‐scale pure shear foreland deformation of western Argentina

    Creator:
    Meigs, Andrew J. and Nábělek, John
    Abstract:
    New analyses of teleseismic body waves from moderate earthquakes in western Argentina demonstrate that active shortening of the Andean foreland occurs on reverse faults extending to 40–50 km depth. Existing crustal‐scale models of foreland deformation invoke thin‐skinned fault geometries, which root into an east‐dipping mid‐crustal décollement. Whereas thin‐skinned thrust sheets...
