Formation
Graywacke rock is a type of sedimentary rock, which is also known as immature sandstone, which is indurated, dark grey and consisting of poorly sorted angular to sub-angular, sand-sized grains.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
