Metamorphic Rocks

What are factors that can cause metamorphism

Pressure, Chemically Active fluids, and time

What are changes a rock undergoes during metamorphism

The textural the arrangement and size of the mineral grains can change. Chemical changes through chemical reactions.

What is Foliation

the alignment of flat or elongated minerals within a rock that have a layered or banded appearance.

What is Metamorphic grade and significance

refers to the intensity of metamorphism a rock has undergone. It helps determine the types of minerals present and the rock’s formation history.

What is Metamorphic facies

a set of metamorphic mineral assemblages formed under specific pressure and temperature conditions.

What are two types of metamorphism

Regional and Contact

What is Regional Metamorphism

Occurs over large areas under high pressure and temperature, typically associated with tectonic forces.

What is Contact Metamorphism

Occurs when rocks are heated by proximity to molten magma or lava, often affecting a smaller area

What are plate tectonic settings that metamorphism can occur

Convergent, Divergent, Transform

What boundary does contract metamorphism occur

Divergent Boundaries

What boundary does regional metamorphism occur

Convergent Boundaries

Where does low grade metamorphism occur

Transform Boundaries
