Definition
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas
Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition

Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
Felsite 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 Felsite Properties
Know all about Laterite and Felsite properties here. All properties of rocks are important as they define the type of rock and its application. Laterite belongs to Sedimentary Rocks while Felsite belongs to Igneous Rocks.Texture of Laterite is Earthy, Massive, Porphyritic whereas that of Felsite is Arborescent Patterned, Vitreous. Laterite appears Rough and Banded and Felsite appears Layered, Banded, Veined and Shiny. The luster of Laterite is dull while that of Felsite is vitreous. Laterite is available in brown, buff, red colors whereas Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors. The commercial uses of Laterite are an oil and gas reservoir, source of bauxite, used in aquariums and that of Felsite are mirror, jewelry.
