Scientific paper

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 dominate shallow-crustal structure, seismological and geological data illustrate that planar reverse faults and pure-shear deformation involving more than 75% of the crust characterizes this thick-skinned structural province.
