Abstract
During the early evolution of some fold mountain belts old listric normal faults in a stretched and thinned basement beneath the sedimentary column may become reactivated as thrust faults. The reversal of motion on these faults allows considerable shortening to occur without subduction or excessive thickening of continental crust. This reactivation hypothesis is supported by the present-day seismicity of the Zagros collision zone and the structure of sedimentary basins.
