What does regional-metamorphism mean? A type of metamorphism in which the mineralogy and texture of rocks are changed over a wide area by deep burial and heat regional metamorphism [A general term for metamorphism affecting an extensive region, as opposed to local metamorphism that is effective only in a relatively restricted area. As introduced in the nineteenth century, the term covered only those changes due to deep burial metamorphism, today it is used almost synonymously with dynamothermal metamorphism ] Regionalmetamorphose f The metamorphism in Nova Scotia’s Meguma Terrane is just one example of the nature of regional metamorphism. Obviously many different patterns of regional metamorphism exist, depending on the parent rocks, the geothermal gradient, the depth of burial, the pressure regime, and the amount of time available.

Regional metamorphism largely  We shall refer in this paper to facies, but we shall do so only in defining areas of PT space that rocks may pass through on the PTt paths of regional metamorphism. minerals in metamorphic rocks." pressure or compressive stress of regional metamorphism does. sedimentary rock, but a low grade metamorphic rock. The facies of regional metamorphism are usual- ly considered as sequential transitions from some mineral associations to others depending on temperature and  Types of Metamorphism. There are two major kinds of metamorphism: regional and contact. Regional metamorphism. Most metamorphic rocks are the result of  Feb 24, 2012 Regional metamorphism: Changes in enormous quantities of rock over a wide area caused by the extreme pressure from overlying rock or from  Jun 20, 2003 Regional Metamorphism.

Extreme 2020-04-14 · Regional metamorphism is generally independent of igneous intrusions and tends to happen in places where tectonic forces have compressed the crust and put high pressure on the rocks. Since contact metamorphism requires that the affected rocks exist within a local temperature gradient, it is necessarily limited to small areas.

The Lovisa Stratiform Zn-Pb Deposit, Bergslagen, Sweden

Regional Metamorphism Regional metamorphism occurs over large areas and generally does not show any relationship to igneous bodies. Most regional metamorphism is accompanied by deformation under non-hydrostatic or differential stress conditions. Regional metamorphism can transform shale into slate, then phyllite, then schist, and finally into gneiss. During this transformation, clay particles in shale transform into micas and increase in size. Finally, the platy micas begin to recrystallize into granular minerals.

Se hela listan på study.com Regional or Barrovian metamorphism covers large areas of continental crust typically associated with mountain ranges, particularly those associated with convergent tectonic plates or the roots of previously eroded mountains. Conditions producing widespread regionally metamorphosed rocks occur during an orogenic event. Contact Metamorphism Vs. Regional Metamorphism Contact Metamorphism Vs. Regional Metamorphism. Metamorphism is the solid change in minerals and textures in a pre-existing rock (country rock) due to changing pressure / temperature conditions. Fluids like H2O also have a very important role to play. A definition, an explanation, and a few noteworthy details for regional metamorphism. 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.
