5 Formation

5.1 Formation

Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

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.
