What are the types of rock metamorphism?
Types of metamorphism are Contact Metamorphism Regional Metamorphism Cataclastic Metamorphism Hydrothermal Metamorphism Burial Metamorphism Shock Metamorphism (Impact Metamorphism)
Why are metamorphic rocks formed by contact metamorphism usually not as dense as those formed by regional metamorphism?
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.
Why are metamorphic rocks formed by contact metamorphism usually not dense or resistant?
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.
What is a zone of contact metamorphism called?
A zone of contact metamorphism is called an aureole.
If the sedimentary rock limestone is subjected to metamorphism what metamorphic rock will likely form?
Limestone can metamorphose into marble, a regional metamorphic rock, or into skarn, a contact metamorphic rock.
How is contact metamorphism different from regional metamorphic?
contact metamorphism is what happens when something is really hot. regional metamorphism on the other hand involves much larger packages of rocks.
What are the types of rock metamorphism?
Types of metamorphism are Contact Metamorphism Regional Metamorphism Cataclastic Metamorphism Hydrothermal Metamorphism Burial Metamorphism Shock Metamorphism (Impact Metamorphism)
What two geological processes are involved in changing sedimentary rock to a metamorphic rock?
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.
What are the 4 types of metamorphism?
contact metamorphism, regional metamorphism, dynamic metamorphism
What is the difference between regional and contact 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.
What is 2 types of metamorphic rocks?
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.
On on what basis can metamorphic rocks be identified?
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 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.

How does Burial metamorphism differ from Regional and Contact metamorphism?
Burial metamorphism differs from regional and contact metamorphism in that it is the result of rocks being buried deeper into the earth's crust through tectonic movements.
