regional metamorphism on the other hand involves much larger packages of rocks.
Types of metamorphism are Contact Metamorphism Regional Metamorphism Cataclastic Metamorphism Hydrothermal Metamorphism Burial Metamorphism Shock Metamorphism (Impact Metamorphism)
The two processes resulting from sedimentary into metamorphic rock are known as contact metamorphism and regional metamorphism. Regional metamorphism most notably involves two tectonic plates colliding, while contact metamorphism occurs due to the intrusion of magma.

contact metamorphism, regional metamorphism, dynamic metamorphism
Regional metamorphism is the creation of metamorphic rock from large geographically significant processes like plate tectonics. Contact metamorphism is the creation of metamorphic rock from the proximity of an existing rock to a heat source provided by a plutonic intrusion.

Because contact metamorphism usually occurs because of an increase in temperature. In contrary, regional metamorphism is usually the result of compression. Compression makes a rock more dense.
Metamorphic rocks are formed by the process of extreme heat, pressure and other chemicals. Two types of metamorphism are dynamic which makes the pressure and extreme heat and thermal which is caused by the heat of magma from a volcanic eruption.
Metamorphic rocks can be identified if the rock is foliated or nonfoliated, foliating type, type of metamorphism (contact/regional), and by probable original rock. :)
Contact and regional are terms used to describe two different types of metamorphic rocks. Contact metamorphism occurs when rocks are heated by nearby molten magma, leading to localized changes in mineralogy and texture. Regional metamorphism, on the other hand, involves larger-scale alterations due to high pressure and temperature over broad areas, often associated with tectonic processes like mountain building. Both types of metamorphism result in the formation of metamorphic rocks, which exhibit distinct characteristics from their parent rocks.
Contact metamorphism does not cause profound compaction, which is the reduction in size of the spaces between mineral particles due to increases in pressure. Regional metamorphism causes compaction and possibly recrystallization, increasing the density of the rock.
Metamorphic rocks formed by contact metamorphism are usually not dense or resistant because they are formed at relatively low pressures and temperatures compared to regional metamorphism. The short duration of the heating process in contact metamorphism does not allow for the recrystallization and reorganization of mineral structures that contribute to denser and more resistant rocks. Additionally, the presence of fluids and gases in contact metamorphism can facilitate alteration and weakening of the original rock material.
