Exam 7: Metamorphism and Metamorphic Rocks

The type of metamorphic rock that is formed depends on the pressure, temperature, stress rate, fluids, and original parent rock composition.

A large block of sedimentary rock that has fallen into the top of a magma chamber and become metamorphosed is called ________.

Examine the words and/or phrases for each question below and determine the relationship among the majority of words/phrases. -Choose the option that does not fit the pattern.

Tektites originate in what metamorphic environment?

Uniform high pressure metamorphism of a quartz-rich sediment will generate a foliated rock like slate, phyllite, or schist.

Hornfels facies is characterized by the high pressure mineral glaucophane.

Regional metamorphism is most intense where ________ collide.

What fluid is geologically the most important to the formation of metamorphic rocks?

Hornfels are metamorphic rocks produced at great depths and high temperatures associated with regional metamorphism.

What low-grade metamorphic minerals are typically formed during burial metamorphism?

During metamorphism, what is the major effect of chemically active fluids?

Which of the following forms at a medium grade of regional metamorphism?

What strongly banded and irregularly folded, metamorphic rocks show good evidence for having formed by partial melting?

Muscovite, biotite, and chlorite are common minerals found in phyllites and schists.

Gneissosity is another term for rock cleavage.

Which type of metamorphism occurs specifically in the heated zone around a pluton or other body of magma?

Which one of the following is not genetically associated with the terrestrial impact of an asteroid or large meteorite?

Metamorphic grade refers to ________.

Which is a coarse-grained, high-grade, metamorphic rock with alternating bands or stringers of light and dark minerals?

________ are formed from the impact of an asteroid or meteorite.
