Why Do Metamorphic Rocks Form At Subduction Zones
Why Do Metamorphic Rocks Form At Subduction Zones - The term facies is an objective description of a rock. Web metamorphism occurs when solid rock changes in composition and/or texture without the mineral crystals melting, which is how igneous rock is generated. Web metamorphic rocks formed there are likely to be foliated because of the strong directional pressure (compression) of converging plates. Web subduction zones are associated with the greatest disturbances to the flow of heat from the interior of the earth. Rock of this type is exposed in the san francisco area.) [se] figure 7.18 franciscan complex blueschist rock exposed north of san francisco.
This gives rise to metamorphic rocks with. The blue colour of rock is due to the presence of the amphibole mineral glaucophane. Web metamorphism can be caused by burial, tectonic stress, heating by magma, or alteration by fluids. Web subduction zones are associated with the greatest disturbances to the flow of heat from the interior of the earth. They are much less abundant, than regional or contact metamorphic rocks. Web because fault zones and shear zones are highly localized, rocks that have undergone dynamic metamorphism are not a widespread type of metamorphic rock; « back to glossary index.

Why Do Metamorphic Rocks Form At Subduction Zones Web because fault zones and shear zones are highly localized, rocks that have undergone dynamic metamorphism are not a widespread type of metamorphic rock; Web how do variations in the geothermal gradient affect the depth at which different metamorphic rocks form? Web one of the possible clues to differentiating the two si modes for active and paleo subduction zones is metamorphic soles, which are thin sheets (a few to several hundred meters thick) of. High t/p type ( t / p > 775 °c/gpa, mean t / p ~1105 °c/gpa), intermediate t/p type ( t / p between 775 and 375 °c/gpa, mean t / p ~575 °c/gpa), and low t/p type ( t / p < 375 °c/gpa, mean t / p ~255 °c/gpa). They are much less abundant, than regional or contact metamorphic rocks.
