Numerical Simulation of Regional and Contact Metamorphism Using the Macintosh Microcomputer. Peacock, Simon Muir. Journal of Geological Education, v38 n2 p132-37 Mar 1990. Described is a set of FORTRAN programs, suitable for teaching and research purposes, that simulate contact and regional metamorphism. Equations, examples, program uses, and availability are discussed. (CW) The development of regional metamorphism in areas of thickened continental crust is investigated in terms of the major controls on regional-scale thermal regimes. These are: the total radiogenic heat supply within the thickened crust, the supply of heat from the mantle, the thermal conductivity of the medium and the length and time scales of erosion of the continental crust. The orogenic

What Makes Metamorphic Rocks So Unique?

Metamorphism acts at two scales: regional and local. Regional-scale metamorphism generally occurs deep underground during orogenies, or mountain-building episodes.The resulting metamorphic rocks from the cores of large mountain chains like the Appalachians.Local metamorphism happens at a much smaller level, usually from nearby igneous intrusions.

Shock metamorphism – shock effects. Terms written in italics are in general explained in the Impact Structure and Meteorite Crater Glossary. Upon collision of a large cosmic projectile (asteroid, comet) with the Earth's surface shock waves propagating into the impactor and into the underground belong to the most important processes in this geologically prominent event.

23.09.20197.4 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 to 20 kilometres is required, the areas affected tend to be large—thousands of square kilometres.

regional metamorphism based on index minerals that form at specific pressure-temperature conditions. Wicander and Monroe (2002) Wicander and Monroe (2002) Regional Metamorphism Beginning with a clay-rich parent rock such as shale and tracking its subjection to ever more intense pressure and heat illustrates the sequence of index minerals formed by low- to high-grade regional metamorphism. For

The tectonic forces deform and break the rock, creating openings, cracks, faults, breccias, and zones of weakness along which magmas can rise. Generally speaking, the greater the tectonic forces, the higher the pressures and temperatures affecting a rock mass and the greater the amount of resulting structural deformation and metamorphism.

Metamorphism, which takes place over the wide regions of the crust is known as regional metamorphism. The majority of the regionally metamorphosed rocks takes place in the regions, which have gone through deformation at the time of an orogenic event. Gneiss is only produced by regional metamorphism. Gneiss can be produced by the regional

Shear zone metamorphism: Introduction Shear zone metamorphism: Introduction BROWN, MICHAEL 1984-06-01 00:00:00 UK. In the first paper, Mason considers the inversion of metamorphic isograds in part of the Norwegian Caledonides to have been the result of syn-metamorphic shear zone deformation on the lower limb of a major overfold.

These bodies are generally described as tectonic blocks and their relationship to the Sanbagawa metamorphism is unclear. New findings of foliated eclogite in the Seba and Kotsu areas show that eclogite facies metamorphism is much more widespread than generally thought. Evidence that the foliated eclogite units originated as lavas or sediments implies that these units can be treated as a

Regional metamorphism is associated with the major events of Earth dynamics, and the vast majority of metamorphic rocks are so produced. They are the rocks involved in the cyclic processes of erosion, sedimentation, burial, metamorphism, and mountain building (orogeny), events that are all Read More; Load Next Article Inspire your inbox – Sign up for daily fun facts about this day in

Whenever metamorphism occurs in the compressional environment of continental collision zones (regional metamorphism), the rock is also subject to directed pressure and this also has an effect on the way the minerals crystallise. In the case of the metamorphism of mudrocks, mica crystals are formed during metamorphism. Mica crystals are characteristically platy in shape, which reflects the fact

This encourages metamorphism.
