Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas

Wehrlite 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.
