Thid project will investigate the interrelationship of deformation and fluid expulsion along the Oregon margin and specifically examine the transition from stratigraphically controlled to fault controlled flow; existing measurements ofintergranular permeability provide a basis for quantifying fluid flow along stratigraphically-controlled conduits; evaluation of the effect of faults will require direct measurements of permeability in fault rocks as well as estimation of permeability along larger-than-sample size fracture networks. They will sample a canyon wall what exposes a fault that is venting fluids; they will determine the variation of permeability, porosity, grain size, cementation state, and structural fabric development across the fault zone.
