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