Question

Quizplus · Accepted Answer

Without an actual map to reference, the correct answer cannot be determined based on the provided information. However, in the context of metamorphic facies or zones, biotite, kyanite, and muscovite are common minerals that indicate specific conditions of pressure and temperature during metamorphism. Quartz, while common in metamorphic rocks, is not typically used to define a specific metamorphic zone due to its stability over a wide range of conditions.
