A recently developed model for thrust belts requires that the              thrust wedge deform internally to attain and maintain a critical                taper angle during fault development.  Although a number of                     mechanisms are known that would accomplish this, the model has                  been questioned on the grounds that there is a lack of extensive                internal deformation and continuous yielding within thrust belts                and that there is evidence that thrusts develop in piggy-back                   fashion.  This study seeks to determine if taper angle-maintaining              mechanisms operate in sufficient magnitude to allow the wedge                   model to function.  Fault sequences in both the Rocky Mountains                 and the southern Appalachians will be studied and sequentially                  restored from balanced cross-sections and results compared to                   products predicted from forward modeling with the original                      section.  Results are expected to establish the viability of the                wedge model for thrust sheet emplacement.
