5 Formation

5.1 Formation

Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

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.
