Magnetic fabric of Late Jurassic arc plutons and kinematics of terrane accretion in the Blue Mountains, northeastern Oregon
Original language description
The Blue Mountains Province of northeastern Oregon, western Idaho, and southeastern Washington (USA) consists of the amalgamated Wallowa distal island arc, Baker melange-bearing accretionary wedge-forearc, and Olds Ferry fringing island arc terranes. Anisotropy of magnetic susceptibility (AMS) and particularly the orientation of magnetic lineations in Middle to Late Jurassic diorite-tonalite-granodiorite plutons intruding the Baker terrane indicate a change in tectonic regime from flattening with principal stretching at a high angle to the local orientation of the terrane boundaries at around 160 Ma to constriction with boundary-subparallel subhorizontal stretching at ca. 146 Ma. The former magnetic fabric is compatible with magnetic lineations recording strain related to top-to-the-southwest back-thrusting onto the Olds Ferry arc. In contrast, the similar to 146 Ma boundary-parallel stretching may record strain partitioning whereby a part of the Baker terrane was extruded laterally pa
