WebThere are two major kinds of metamorphism: regional and contact. Regional metamorphism. Most metamorphic rocks are the result of regional metamorphism (also called dynamothermal metamorphism). These rocks were typically exposed to tectonic forces and associated high pressures and temperatures. WebApr 10, 2024 · These rocks are created by regional metamorphism where the microscopic grains of the rock combine to form larger crystals. There is a large variety in the color of these rocks, with some being a pure white, and others being a dark black. Most marbles are a combination of a lighter and darker color.
