Question

Quizplus · Accepted Answer

The rapid and deep burial of sediments in an accretionary prism can lead to the formation of blueschist, a metamorphic rock characterized by blue minerals such as glaucophane or amphibole. This occurs due to the high-pressure conditions prevalent in the subduction zone environment. The other three options, greenschist, migmatite, and gneiss, are metamorphic rocks that form under different conditions and are not typically associated with accretionary prisms.
