WebCritical-wedge models for foreland thrust belts, although popular paradigms for thrust mechanics, also predict definite progressive changes within the orogenic belt. The most important constraint on critical-wedge models is the need for deformation of the interior of the wedge when new sheets are accreted to its front. Well-dated foreland ...
