1 Formation
1.1 Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Gneiss is a high grade metamorphic rock i.e. it has been subjected to higher temperatures and pressures than schist. It is formed by the metamorphosis of Gneiss forms from volcanic rock, shale or granitie.
