Metamorphic Rocks | Pictures of Foliated and Non-Foliated Types
Metamorphic rocks have been modified by heat, pressure, and chemical processes, usually while buried deep below Earth's surface. Exposure to these extreme conditions has altered the mineralogy, texture, and chemical composition of the rocks. There are two basic types of metamorphic rocks.

6 Metamorphic Rocks – An Introduction to Geology
Metamorphic source rocks, the rocks that experience the metamorphism, are called the parent rock, or protolith, from proto – meaning first, and lithos- meaning rock. Most metamorphic processes take place deep underground in earth’s crust.
3.8: Metamorphic Rocks - Geosciences LibreTexts
Metamorphic rock fall into two categories, foliated and unfoliated. Most foliated metamorphic rocks originate from regional metamorphism. Some unfoliated metamorphic rocks, such as hornfels, originate only by contact metamorphism, but others can originate either by contact metamorphism or by regional metamorphism.
