Formation

Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.   
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Pseudotachylite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Laterite vs Pseudotachylite 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 Laterite and Pseudotachylite Reserves. Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas. Very fine grained fault rock which is composed of glassy matrix that often contains inclusions of wall-rock fragments.. 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 Laterite vs Pseudotachylite information and Laterite vs Pseudotachylite characteristics in the upcoming sections.
