| Abstract | Brittle structures in the Coast Mountain region of northern Cascadia record a history of inhomogeneous deformation that may shed light on the Neogene crustal response to oblique subduction and dextral
transcurrent faulting along the Cordilleran plate margin of western North America. Structures in the intra-arc and backarc regions record an older Paleogene history of dextral transpression, and a Neogene history of orogen-parallel compression that
likely reflects distributed Pacific/North American plate motions, and the effects of mechanical buttressing at the leading edge of the southern Cascadia forearc. Structures in the northern Cascadia forearc record effects of both orogen-normal and
orogen-parallel compression, likely associated with oblique subduction of the Juan de Fuca plate. The pattern and history of strain partitioning provide an important framework for natural hazards assessment, and for exploration of natural resources
that may be localized, in part, by brittle faulting and fluid migration in the upper crust. |
