5 Formation

5.1 Formation

Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.

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