5.1 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.

Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
