6 Formation
6.1 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.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
