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.

Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
