Deposition

The process in which material is laid down

Stratification

The process in which sedimentary rocks are arranged in layers

Contact Metamorphism

being heated by nearby magma and near igneous intrusions

Regional Metamorphism

When pressure builds up in rock that is buried deep below other rock formations or when large pieces of the Earth's crust collide with each other

Index Minerals

Are used to estimate the temperature, depth, and pressure in which a rock undergoes metamorphism.

Foliated

The texture of metamorphic rock in which the mineral grains are arranged in planes or bands

Nonfoliated

The texture of metamorphic rock in which the mineral grains are not arranged in planes or bands
