Define regional and contact metamorphism
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 ...
