5 Formation

5.1 Formation

Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Further, the Oceanic crust is hydrothermally altered as quartz and sodium are added.

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