Definition
Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas

Formation
Epidosite 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.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

All about Epidosite and Laterite Properties
Know all about Epidosite and Laterite properties here. All properties of rocks are important as they define the type of rock and its application. Epidosite belongs to Igneous Rocks while Laterite belongs to Sedimentary Rocks.Texture of Epidosite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular whereas that of Laterite is Earthy, Massive, Porphyritic. Epidosite appears Dull and Soft and Laterite appears Rough and Banded. The luster of Epidosite is not available while that of Laterite is dull. Epidosite is available in black, brown, light to dark grey colors whereas Laterite is available in brown, buff, red colors. The commercial uses of Epidosite are commemorative tablets, creating artwork and that of Laterite are an oil and gas reservoir, source of bauxite, used in aquariums.
