Definition

Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas

Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass

Formation

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

Shoshonite 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.
