Formation

Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.

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