Differentiate volcanism and metamorphism

WebFour common types of foliated metamorphic rocks, listed in order of metamorphic grade or intensity of metamorphism are slate, phyllite, schist (pronounced “shist”), and gneiss (pronounced “nice”). Each of these has a characteristic type of foliation. Slate. Slate (Figure 10.14) forms from the low-grade metamorphism of shale. WebMay 6, 2024 · Regional metamorphism also takes place within volcanic-arc mountain ranges, and because of the extra heat associated with the volcanism, the geothermal gradient is typically a little steeper in these settings (somewhere between 40° and 50°C per kilometre). As a result higher grades of metamorphism can take place closer to surface …

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.
