Regional Metamorphism: Diagrams, Rocks, Examples - Geology In
Regional metamorphism is a type of metamorphism that occurs over a wide area, typically hundreds to thousands of square kilometers. It is caused by the combined effects of heat, pressure, and stress associated with large-scale tectonic processes, such as mountain building and continental collisions.
Contact Vs. Regional Metamorphism - Geology In
Contact Metamorphism and Regional Metamorphism are two main types of metamorphism where rocks are altered due to changes in temperature, pressure, and chemically active fluids. Regional metamorphism takes place over a much wider area. Contact metamorphism is taking place when magma is injected in the surrounding solid rock (country rock ...

2022年8月28日 · Regional metamorphism occurs because both pressure and temperature increase with depth in Earth (Figure 8.3). The deeper the rocks, the greater the metamorphism. The photos below show two outcrops of regional metamorphic rocks.

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. The important point is that regional metamorphism happens only at significant depths.

Rather than focusing on metamorphic rock textures (slate, schist, gneiss, etc.), geologists tend to look at specific minerals within the rocks that are indicative of different grades of metamorphism. Some common minerals in metamorphic rocks are shown in Figure 7.21, arranged in order of the temperature ranges within which they tend to be stable.

7.4 Regional Metamorphism – Physical Geology – 2nd Edition
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.
