D)blueschist

Question

Quizplus · Accepted Answer

Hornfels is a typical facies associated with high temperature-low pressure contact metamorphism. This type of metamorphism occurs when rocks are altered by the heat from an igneous intrusion, but there is relatively low pressure due to the shallow depth of the rocks. Hornfels is a fine-grained, hard rock that forms in response to this type of metamorphism, and is often associated with contact aureoles around igneous intrusions. Amphibolite, granulite, and blueschist are all associated with higher pressure metamorphism and are therefore not as likely to be found in this context.
