5 Formation

5.1 Formation

Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
