Major arc-parallel displacements occurred along high-temperature (700 °C) ductile normal faults and steep sinistral transtensional shear zones within an obliquely convergent margin. Strain patterns and pluton emplacement were controlled by (1) structural anisotropies in host rocks that predate batholith emplacement, and (2) kinematic compatibility requirements created by simultaneous motion on curved, pluton-bounding shear zones. These controls superseded a partitioning of the arc-parallel and arc-normal components of oblique-plate convergence onto strike-slip and thrust faults, respectively. This content is PDF only.
