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.

The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

Blueschist vs Appinite 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 Appinite Reserves. Blueschist is a metamorphic rock which is generally blue in color and is formed under conditions of high pressure and low temperature. Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished. 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 Appinite information and Blueschist vs Appinite characteristics in the upcoming sections.
