This grant will support continued work on the mechanics of                 sedimentary wedges.  The PIs have developed a kinematic and                     thermal model of an eroding critically tapered fold-and-thrust                  belt, using the steady-state fold-and-thrust belt in western                    Taiwan as the center piece of modelling efforts.  The principal                 new project is to extend mechanical and thermal models to the                   extensional counterparts of compressive wedge, namely the normally              faulted wedges of material that overly shallow angle detachment                 faults.  The PIs have developed a critical taper model of these                 structures which (like the model of a compressional wedge)                      requires good structural and especially pore-fluid pressure data                to be tested.  They have recently acquired an extensive set of                  industrial seismic and drilling data from the Brazos Ridge                      extensional wedge in the Gulf of Mexico for this purpose.  They                 will develop a complete mechanical, kinematic and thermal model of              an extensional wedge, using the Brazos wedge as the main example.
