What is blueschist facies?

Answer

Blueschist facies is a low to average-grade characterized by low heats and associated with subduction. Blueschist facies is determined by the particular heat-Force situations required to convert basalt to form blueschist. Blueschist is a metavolcanic rock that forms by the metamorphism of basalt and pillars with similar arrangement at high forces and low heats, approximately parallel to a distance of fifteen to thirty kilometers.
