Answer:
accretionary wedge
Explanation:
Accretionary wedge is a form of tectonic setting, which describes sediments, formed at the top of material on a tectonic plate, that formed together and break where oceanic and continental plates hit into each other.
It is characterized by having strength that is similar to that of the formation on existing thrust faults in the wedge
Hence, in this case, the tectonic setting that would be assign to these rocks is ACCRETIONARY WEDGE.
