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.

Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
