Metamorphic zone - Wikipedia
Barrovian metamorphism takes place during regional metamorphism, caused by crustal thickening in the roots of an orogenic belt (under mountain chains). Barrovian zones are especially easy to recognize in pelitic rocks.
14 Metamorphism of Pelitic Rocks – Open Petrology
These minerals form in pelitic rocks when metamorphism occurs at conditions on a Barrovian P-T path, shown by a black arrow in Figure 14.3. (See also Figure 13.4, and the discussion of metabasites and facies series in Chapter 13). Barrovian metamorphism is the most common kind of metamorphism.
Barrovian metamorphism - James Madison University
2000年10月25日 · Barrovian metamorphism is the most commonly encountered. It occurs in intense tectonic conditions associated with volcanic arcs, and major mountain building. Barrovian metamorphism is widely found across time and space on all parts of the earth, and produces the most common metamorphic rocks.
Metamorphic series - Wikipedia
Metamorphic series include the Barrovian and Buchan series of metamorphic rocks. George Barrow was a geologist in Scotland who discovered the Barrovian series. [1] These are also called metamorphic facies series.
Regional Metamorphism - Tulane University
Regional metamorphism is metamorphism that occurs over broad areas of the crust. Most regionally metamorphosed rocks occur in areas that have undergone deformation during an orogenic event resulting in mountain belts that have since been eroded to expose the metamorphic rocks.

Origin of Regional Barrovian Metamorphism in Hot Backarcs ...
2018年11月20日 · This article presents evidence that the high temperatures responsible for much regional metamorphism, the Barrovian sequence, occurs in subduction zone backarcs prior to and not, as commonly inferred, as a consequence of heating during continental collision orogeny.

2021年12月1日 · Microstructural analysis shows that Barrovian garnet, staurolite and kyanite grew synchronously with the earliest regional metamorphic foliation S1 B. A sillimanite-bearing assemblage locally overprinted the assemblage of the staurolite zone in a foliation parallel with S1 B, assigned as S1 M.
