Archaeological Significance
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. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
