Definition

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

Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

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.

Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
