5 Formation

5.1 Formation

Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.
