Definition of regional metamorphism in English:
Metamorphism affecting rocks over an extensive area as a result of the large-scale action of heat and pressure. Compare with contact 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.
- Field relations indicate that intrusion post-dated the peak of regional metamorphism and the main foliation-forming event.
- One occurrence seems unrelated to igneous activity and may be the result of regional metamorphism of dolomite- and anhydrite-rich evaporites.
