Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.

All about Laterite and Itacolumite Properties
Know all about Laterite and Itacolumite properties here. All properties of rocks are important as they define the type of rock and its application. Laterite and Itacolumite belong to Sedimentary Rocks.Texture of Laterite is Earthy, Massive, Porphyritic whereas that of Itacolumite is Clastic, Granular, Rough. Laterite appears Rough and Banded and Itacolumite appears Rough. The luster of Laterite and Itacolumite is dull. Laterite is available in brown, buff, red colors whereas Itacolumite is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. The commercial uses of Laterite are an oil and gas reservoir, source of bauxite, used in aquariums and that of Itacolumite are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones.
