Formation of Metamorphic Rocks Large tectonic movements and magma intrusions create earth movements and subsequently cause the pre-existing rocks to move and shift. In turn, the movements subject other rocks buried deep below the earth's surface to extreme pressure and heat which contributes to changes and assemblage of the rocks texture, mineralogy, and chemical composition.

Metamorphic rock - Pressure | Britannica

Metamorphic rock - Metamorphic rock - Pressure: The pressure experienced by a rock during metamorphism is due primarily to the weight of the overlying rocks (i.e., lithostatic pressure) and is generally reported in units of bars or kilobars. The standard scientific notation for pressure is expressed in pascals or megapascals (1 pascal is equivalent to 10 bars).

Formation of metamorphic rocks - EARTH.RICE.EDUDeze pagina vertalen

Formation of metamorphic rocks Metamorphic rocks are created by the physical or chemical alteration by heat and pressure of an existing igneous or sedimentary material into a denser form. Due to the action of plate tectonics, compression, stress and shearing forces over long periods of time, rocks can be essentially warped and deformed, causing them to be compacted into a smaller volume of space.
