Define regional and contact metamorphism
WebThe meaning of REGIONAL METAMORPHISM is geological metamorphism involving a wide area. WebMetamorphism is a geological process that causes rocks to change due to exposure to heat, pressure, or other factors. This process is typically classified into two categories: regional metamorphism and contact metamorphism. However, there are also several other classifications based on different factors. For example, hydrothermal …

WebContact metamorphism (also called thermal metamorphism) is the process by which the country rock that surrounds a hot magma intrusion is metamorphosed by the high heat … WebContact metamorphism is caused by igneous intrusions as a result of the thermal effects of hot magma on the surrounding cooler country rock. Temperatures may be up to 1000 °C at relatively low pressures (0.05–0.5GPa). Pyrometamorphism is a special form of contact metamorphism at very high temperatures (> 1000 °C) and very low pressures (< 0 ...
