Timing of subduction initiation and deformation history of amphibolite and blueschist in the Easton metamorphic suite, Northwest Cascades, Washington [PDF]

open access: yes
High-temperature metamorphic soles form in nascent subduction zones when a thin sliver of newly subducting oceanic plate is accreted and metamorphosed by the overlying mantle. The Easton metamorphic suite is a Jurassic to Cretaceous subduction complex in
