A)A rock that forms at specific metamorphic conditions and can be used to determine the metamorphic style
B)Textural transitions based on the direction and amount of pressure
C)Zones of contact metamorphism along an intrusive igneous rock

Question

Quizplus · Accepted Answer

A metamorphic facies is an assemblage of minerals that form in very similar metamorphic environments, characterized by a specific set of pressure-temperature conditions. These conditions reflect a balance between the heat and pressure applied to a rock and the chemical environment in which the rock is changed. Therefore, choice D is the best answer.
