Formation

Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

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.
