Quaternary-active thrusts scarps tested as deformation markers by trishear models in the Southern Precordillera of Argentina

Trishear models predict shortening values 8 to 15 times larger than those obtained through line retrodeformation of scarp profiles. Therefore, scarp shapes at a mesoscopic scale in the study area, are not considered a reliable deformation marker for shortening estimation of propagating thrusts through an unconsolidated cover.
