ASIA: hypercollision tectonics

Metamorphic rocks that developed by recrystallization on a regional scale over large areas, hundreds of km 2 in extent, are the products of regional metamorphism.Three genetic types are distinguished: (1) regional dynamothermal metamorphism, (2) regional burial metamorphism, and (3) regional geothermal metamorphism.

A type of metamorphism in which the mineralogy and texture of rocks are changed over a wide area by deep burial and heat 2020-06-09 If (a) regional metamorphism is substantially a response of these preexisting crystalline particles to a rise in temperatures, (b) the different crystal structures respond at different temperatures, and (c) such temperatures vary in space and time, then it may be expected that the various relevant metamorphic daughter products will develop in Where both heat and pressure play a role, the mechanism is termed regional metamorphism. 2017-09-01 2015-08-05 Regional Metamorphism To maintain the sustained unidirectional movement of Pangea northwards followed by the east and westward movements of crustal plates either side of the central part of the African plate, the applied forces have to be both substantial and have a stable permanent origin. The metamorphism in Nova Scotia’s Meguma Terrane is just one example of the nature of regional metamorphism.

Borevskiy et al., 1984; its host rocks, both immediately after emplacement of the apatite-iron oxide body, and during subsequent phases of regional metamorphism and deformation.

Regional metamorphism is primarily due to tectonic forces associated with the interaction between lithospheric plates. This occurs in areas of active subduction and mountain building.

Rocks that form from regional metamorphism are likely to be foliated because of the strong directional pressure of converging plates. The Himalaya range is an regional metamorphism. « Back to Glossary Index · Metamorphism that occurs with large-scale tectonic processes, like collision zones. Related Articles:.

Regional metamorphic rock results from regional metamorphism and usually develops a flaky texture. It is distributed most widely in metamorphic rock, from Archean to even Cenozoic. Regional metamorphism occurs when rocks are buried deep in the crust. This is commonly associated with convergent plate boundaries and the formation of mountain ranges. Because burial to 10 km to 20 km is required, the areas affected tend to be large. Most regional metamorphism takes place within continental crust.

Regional Metamorphism of Ore Deposits and Genetic Implications

They are the rocks involved in the cyclic processes of erosion, sedimentation, burial, metamorphism, and mountain building (orogeny), events that are all… Regional metamorphism Regional metamorphism is associated with the major events of Earth dynamics, and the vast majority of metamorphic rocks are so produced. 7.4 Regional Metamorphism As described above, regional metamorphism occurs when rocks are buried deep in the crust. This is commonly associated with convergent plate boundaries and the formation of mountain ranges. Because burial to 10 km to 20 km is required, the areas affected tend to be large. As described above, regional metamorphism occurs when rocks are buried deep in the crust. This is commonly associated with convergent plate boundaries and the formation of mountain ranges.

Regional and contact metamorphism account for most metamorphic rocks. Dynamic metamorphism is in a distant third place. Some geologists have also described another kind of metamorphism, called burial metamorphism, but it is really just high-temperature diagenesis. 8.1.1 Prograde vs Retrograde Metamorphism 4.2.4 High-pressure metamorphism and its geological consequences 81 4.2.5 Ultra-high-pressure (UHP) metamorphism 82 4.3 Shock metamorphism 84 4.3.1 The discovery of shock metamorphism 84 4.3.2 Products of giant impacts 84 4.3.3 Extra-terrestrial shock metamorphism 86 5 Case studies in geothermobarometry 89 5.1 Granulite-facies rocks at Slishwood 89 Textural variations caused by regional metamorphism Idealized illustration of textural variations produced by regional metamorphism, progressing from low-grade metamorphism (slate) to high grade metamorphism (gneiss).
