5 Formation

5.1 Formation

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.

Foidolites is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Blueschist vs Foidolite 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 Blueschist and Foidolite Reserves. Blueschist is a metamorphic rock which is generally blue in color and is formed under conditions of high pressure and low temperature. Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%. 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 Blueschist vs Foidolite information and Blueschist vs Foidolite characteristics in the upcoming sections.
