Formation

Greenschist is medium grade metamorphic rock, formed by the metamorphosis of mudstone or shale, or some types of igneous rock, when it is subjected to higher temperatures and pressures.

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