Question

Quizplus · Accepted Answer

The blueschist facies is a low-temperature, high-pressure metamorphic environment typically formed at depths of 15 to 30 km and pressures of 0.5 to 2.5 GPa (5 to 25 kbar). The relatively low temperature is due to the ability of water to circulate in subduction zones, allowing for minerals to form that are indicative of this facies.
