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.

Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
