Definition
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals

Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
Carbonatites are intrusive or extrusive igneous rocks which are defined by mineralogic composition consisting of greater than 50 percent carbonate minerals and are formed due to low degrees of partial melting of rocks.

All about Laterite and Carbonatite Properties
Know all about Laterite and Carbonatite properties here. All properties of rocks are important as they define the type of rock and its application. Laterite belongs to Sedimentary Rocks while Carbonatite belongs to Igneous Rocks.Texture of Laterite is Earthy, Massive, Porphyritic whereas that of Carbonatite is Granular, Poikiloblastic. Laterite appears Rough and Banded and Carbonatite appears Dull, Banded and Foilated. The luster of Laterite is dull while that of Carbonatite is subvitreous to dull. Laterite is available in brown, buff, red colors whereas Carbonatite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Laterite are an oil and gas reservoir, source of bauxite, used in aquariums and that of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux.
