The process of rock metamorphism changes the mineralogical and chemical composition, as well as the structure of rocks. Metamorphism is typically associated with elevated temperature and pressure; thus it affects rocks within the earth's crust and mantle. The process is driven by changing physical ...
This process, known as metamorphism, occurs deep within the Earth's crust where temperatures and pressures are high. The other options, cooling of magma, compaction of sediments, and melting of rock, are processes that lead to the formation of other types of rocks such as igneous and ...

Metamorphic rocks are rocks that started out either as igneous or sedimentary but have gone through significant chemical and physical changes. Metamorphism occurs when a protolith (original rock) endure high temperature (sometimes close to 300 °C) and pressure (near 1000 bar). Rocks which are alr...
Gneiss ("nice") is a rock of great variety with large mineral grains arranged in wide bands. It means a type of rock texture, not a composition. This type of metamorphic was created by regional metamorphism, in which a sedimentary or igneous rock has been deeply buried and subjected to hi...
Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means “change in form.” Metamorphic rocks make up a large part of the Earth’s crust and form 12% of the Earth’s land surface. They are classified by texture and by chemical ...
Hornfels is a rock that was "baked" while near a heat source such as a magma chamber, sill, or dike. The specimen shown above is about two inches (five centimeters) across.ADVERTISEMENT Marble is a non-foliated metamorphic rock that is produced from the metamorphism of limestone or ...

When shale undergoes greater heat and pressure, it becomes the metamorphic rock slate. With still more metamorphism, it becomes phyllite and then schist. 23 of 24 Siltstone Siltstone is a rock that's made of sand and clay sediment. ThoughtCo / Andrew Alden ...
