5 Formation

5.1 Formation

Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.

Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.

Migmatite vs Blueschist Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Migmatite and Blueschist Reserves. Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components. Blueschist is a metamorphic rock which is generally blue in color and is formed under conditions of high pressure and low temperature. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Migmatite vs Blueschist information and Migmatite vs Blueschist characteristics in the upcoming sections.
