The most likely place for a high temperature metamorphic belt along an Andean margin is among the volcanic debris and deformed accretionary wedge materials over the oceanic slab.

Question

Quizplus · Accepted Answer

High temperature metamorphic belts along an Andean margin are most likely to be found in the continental crust above the subducting oceanic slab, where the heat from the subducting slab and associated magmatic activity can cause high-grade metamorphism, rather than among the volcanic debris and deformed accretionary wedge materials over the oceanic slab.
