Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Laterite and Latite Properties
Know all about Laterite and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Laterite belongs to Sedimentary Rocks while Latite belongs to Igneous Rocks.Texture of Laterite is Earthy, Massive, Porphyritic whereas that of Latite is Aphanitic to Porphyritic. Laterite appears Rough and Banded and Latite appears Rough. The luster of Laterite is dull while that of Latite is subvitreous to dull. Laterite is available in brown, buff, red colors whereas Latite is available in black, brown, 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 Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
