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.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
