5 Formation

5.1 Formation

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

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.
