5 Formation

5.1 Formation

Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.

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