5 Formation

5.1 Formation

Harzburgite 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.

Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
