1.1 Definition

Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth

Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism

5 Formation

5.1 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.

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