5 Formation

5.1 Formation

Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.

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