https://en.wikipedia.org/wiki/Metamorphic_rockMetamorphic rocks arise from the transformation of existing rock to new types of rock, in a process called metamorphism. The original rock (protolith) is subjected to temperatures greater than 150 to 200 °C (300 to 400 °F) and, often, elevated pressure of 100 megapascals (1,000 bar) or more, causing

https://simple.wikipedia.org/wiki/Metamorphic_rockA metamorphic rock is a type of rock which has been changed by extreme heat and pressure. Its name is from 'morph' (meaning form), and 'meta' (meaning change). The original rock gets heated (temperatures greater than 150 to 200 °C) and pressured (1500 bars ). This causes profound physical and/or chemical change.

Metamorphism - Wikipedia
https://en.wikipedia.org/wiki/MetamorphismMetamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). The change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. The chemical components and crystal structures of the minerals making up the rock may change even though the rock remains a solid. Changes at or just beneath Earth's surface due to

Some examples of metamorphic rocks are Gneiss, Slate, Marble, Schist, and gneiss.
Metamorphic zone - Wikipedia
https://wiki-mirror.cla.umn.edu/wiki/Metamorphic_zoneA metamorphic zone is the region between two such easily recognizable isograds. Often they are named for the most characteristic index mineral of the zone. Whether a certain index mineral occurs is also dependent on the composition of the rock itself. Many index minerals have complicated chemical compositions.
Metamorphic rock - McGill University
https://www.cs.mcgill.ca/.../wp/m/Metamorphic_rock.htm- Metamorphic minerals are those that form only at the high temperatures and pressures associated with the process of metamorphism. These minerals, known as index minerals, include sillimanite, kyanite, staurolite, andalusite, and some garnet. Other minerals, such as olivines, pyroxenes, amphiboles, micas, feldspars, and quartz, may be found in metamorphic rocks, but ar…

Metamorphic Rock Types: Pictures and Descriptions
https://www.thoughtco.com/metamorphic-rock-types-412298113/03/2009 · Metamorphic rocks are an important topic in geology. These are the rocks that form by the effects of heat, pressure, and shear upon igneous and sedimentary rocks. Some form during mountain-building by forces of others from the heat of igneous intrusions in regional metamorphism others from the heat of igneous intrusions in contact metamorphism.
