The research involves a field-based study of the processes of subduction        underplating, ductile thickening and uplift as exposed within the               Olympic Core rocks, a Cenozoic accretionary complex in the Olympic              Mountains of NW Washington.  Geological and geophysical evidence                indicates that the eastern Core rocks were accreted beneath the                 accretionary wedge at a distance of at least 50 km from the trench.             Therefore, this area provides a unique opportunity to directly study            deformational processes within the more landward and deeply seated part         of a sediment-rich accretionary complex.  The study will combine                techniques of structural geology, metamorphic petrology and fission-            track dating to determine (1) the process of underplating, whether by           imbricate faulting or by wholesale flowage; (2) the amount and nature of        post-accretion ductile strain using finite-strain measurements and              deformational textures; (3) the maximum depth of structural burial as           indicated by peak metamorphic grade; and (4) the time and rate of uplift        using fission-track dating.  Potential contributions include:  (1) a            better understanding of how accretionary wedges grow and how high-              pressure metamorphic rocks are returned to the surface; (2) direct              information about flow mechanisms within the wedge, which is critical to        geomechanical modelling of wedges; and (3) new tools and concepts for           mapping and interpretation of older subduction complexes.
