Burial metamorphism takes place simply through rock being buried to great depths below the Earth's surface in a subsiding basin.{{sfn|Yardley|1989|p=12}} Here the rock is subjected to high temperatures and the great pressure caused by the immense weight of the rock layers above. Burial metamorphism tends to produce low-grade metamorphic rock. This shows none of the effects of deformation and folding so characteristic of dynamothermal metamorphism.{{sfn|Robinson|Bevins|Aguirre|Vergara|2004 |pp=513–528}}

Examples of metamorphic rocks formed by burial metamorphism include some of the rocks of the [[Midcontinent Rift System]] of North America, such as the [[Sioux Quartzite]],{{sfn|Denison|Bickford|Lidiak|Kisvarsanyi|1987}} and in the [[Hamersley Basin]] of Australia.{{sfn|Smith|Perdrix |Parks |1982}}
