5 Formation

5.1 Formation

Hornblendite 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.

Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.
