What kind of force will create foliation in metamorphic rocks?

Metamorphic rocks can sometimes contain unusually large grains surrounded by a fine-grained matrix of other minerals.These large crystals are called ________.

Slate and phyllite are similar in appearance.How can the foliation and the shine be used to tell them apart?

What is the texture of this rock?

What is the minimum depth at which subduction zone metamorphism will occur?

________ is the process by which new mineral grains larger than the original mineral grains form as a result of metamorphic heat.

Define metamorphic grade.

Which agent of metamorphism was primarily responsible for generating the rock in the image above?

Compare and contrast how the aureole of contact metamorphism will change in thickness depending on the intrusive igneous structure.

Which kind of stress (confining pressure or differential stress)is responsible for creating the texture visible in this rock?

Explain how migmatites form.Why are they difficult to fit into any of the three basic rock types?

Which of the following is not an environment of metamorphism?
