In which setting would regional metamorphism be most likely and prevalent?
Also asked, what setting is regional metamorphism?
4. Regional Metamorphism (Fig. 8.3): When temperatures and pressures increase beyond the range of burial metamorphism, regional metamorphism takes over. Regional metamorphism takes place under high temperature and pressure conditions that may extend over large areas.
Additionally, where does most hydrothermal metamorphism occur? Much hydrothermal metamorphism occurs at the boundaries of oceanic plates. Plates which are moving apart allow seawater to percolate through the oceanic crust. As the seawater migrates, it heats and reacts with the host rock.
Also Know, where does metamorphism take place?
Most metamorphism takes place in a zone that begins several kilometers below the surface and extends into the upper mantle. Where does most metamorphism take place? Foliated rocks are banded metamorphic rocks that form when minerals realign as the result of pressure from opposing sides.
What is the most prominent feature of regional metamorphic rocks?
The single most distinctive feature of regional metamorphic rocks that separates them from both igneous and sedimentary rocks is the presence of a preferred orientation of the individual minerals that comprise the rock. The term used to describe a preferred orientation is foliation.
