Which metamorphic facies would be highly unlikely to occur in a subduction zone?
A)zeolite
B)blueschist
C)eclogite
D)granulite

Question

Quizplus · Accepted Answer

Granulite facies are typically formed under high temperature and moderate to high pressure conditions, which are not characteristic of the relatively cool, high-pressure conditions found in subduction zones. Instead, subduction zones are more likely to produce metamorphic rocks of the blueschist and eclogite facies due to their high-pressure, low-temperature conditions. Zeolite facies can also occur in relatively low-grade metamorphic conditions typical of some subduction zone environments.
