Definition of regional metamorphism in English:

regional metamorphism

noun

mass nounGeology

Metamorphism affecting rocks over an extensive area as a result of the large-scale action of heat and pressure.
〔地质〕区域变质作用
Example sentencesExamples
- One occurrence seems unrelated to igneous activity and may be the result of regional metamorphism of dolomite- and anhydrite-rich evaporites.
- Field relations indicate that intrusion post-dated the peak of regional metamorphism and the main foliation-forming event.
- Two phases of regional metamorphism are related to their respective episodes of penetrative deformation in the southern Central Iberian Zone.
- The succession has experienced both a low temperature, but relatively high-pressure, regional metamorphism (up to garnet zone) and a phase of earlier hydrothermal metamorphism.
- Orogenic or anorogenic, there was much deformation and regional metamorphism both before and during the intrusion of plutons between 1.36 and 1.47 billion years ago.
