Formation

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

Comendite is a type of Igneous rock which is formed due to cooling and solidification of lava or magma. It may form with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
