5 Formation

5.1 Formation

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.

Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.
