Burial metamorphism refers to the alteration of rocks due to increased pressure and temperature from the weight of overlying sediment. This type of metamorphism occurs at relatively low temperatures and pressures compared to other types, such as regional metamorphism. It commonly occurs in sedimentary rocks buried deep within the Earth's crust.
The rock undergoes metamorphism, where intense pressure and heat cause its mineral composition and texture to change without melting. This process can result in the formation of new minerals and reorganization of existing ones, leading to the development of metamorphic rocks like marble or slate.
Types of metamorphism are Contact Metamorphism Regional Metamorphism Cataclastic Metamorphism Hydrothermal Metamorphism Burial Metamorphism Shock Metamorphism (Impact Metamorphism)
Convergent boundary
When rocks stack on each other, contact metamorphism can occur. This type of metamorphism happens when the high temperature and pressure from nearby molten rock alter the composition of the rocks in contact.
Contact metamorphism is the process of forming rocks from the heat of magma intrusion. Regional metamorphism, meanwhile, is the process of forming rocks by pressure and heat at plate boundaries.
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.
Burial metamorphism.
Zeolite and prehnite-pumpellyite facies are characteristic of burial metamorphism. These facies typically occur at low to medium pressures and temperatures, representing the early stages of metamorphism when sediments are first buried and compacted.

Anthracite forms from the metamorphism of bituminous coal. The metamorphism occurs due to pressures and temperatures from depth of burial or stresses derived from plate movements.
Two processes that can cause metamorphism are heat (from deep burial or nearby magma) and pressure (from burial or tectonic forces). These processes can change the mineralogy, texture, and sometimes the chemical composition of rocks, leading to the formation of metamorphic rocks.
When rocks stack on each other, contact metamorphism can occur. This type of metamorphism happens when the high temperature and pressure from nearby molten rock alter the composition of the rocks in contact.
