Metamorphic Rocks - Geological Society of Glasgow

Metamorphic Minerals. All rocks are composed of minerals, and each mineral is only stable over a particular range of temperatures and pressures. Outwith that range it will tend to break down or combine with a neighbouring mineral to form a new mineral. The process of metamorphism is associated with the formation of particular metamorphic minerals.
