5 Formation
5.1 Formation
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.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
