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.

Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
