1.1 Formation
Gritstone is a type of sedimentary rock which was formed on the floors of wide river deltas where the grit deposits were laid down, with every tide or flood dumping another layer of sediment.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
