Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.
