5 Formation

5.1 Formation

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

Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.
