How might molten rock be generated
WebMagma is molten (melted) rock under the surface of the Earth. It is produced in the upper reaches of the mantle or in the lowest areas of the crust usually at a depth of 50 to 200 kilometers. The diagram above shows you where magma is produced at a subduction zone. Magma is less dense than the surrounding rock which causes it to rise. Webcaused by decompression as hot mantle rock from depth is moved toward the surface (Figure 4.5.3). The triangular zone of partial melting near the ridge crest is approximately 60 km thick and the proportion of magma is about 10% of the rock volume, thus producing crust that is about 6 km thick.

WebMetamorphism therefore occurs at temperatures and pressures higher than 200 o C and 300 MPa. Rocks can be subjected to these higher temperatures and pressures as they become buried deeper in the Earth. Such burial usually takes place as a result of tectonic processes such as continental collisions or subduction.

Web2 apr. 2024 · Magmas evolve in three main ways: they change as they slowly crystallize, mix with other magmas, and melt the rocks around them. Together these mechanisms are called magmatic differentiation. Magma may stop with differentiation, settle down and solidify into a plutonic rock. Or it may enter a final phase that leads to eruption.
