Definition
Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth
Granite is a very hard, granular, crystalline igneous rock which consists mainly of quartz, mica, and feldspar and is often used as building stone

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.
Granite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks

All about Diatomite and Granite Properties
Know all about Diatomite and Granite properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite belongs to Sedimentary Rocks while Granite belongs to Igneous Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Granite is Granular, Phaneritic. Diatomite appears Soft and Granite appears Veined or Pebbled. The luster of Diatomite is dull while that of Granite is dull to grainy with sporadic parts pearly and vitreous. Diatomite is available in grey, white, yellow colors whereas Granite is available in black, grey, orange, pink, white colors. The commercial uses of Diatomite are alumina refineries, animal feed filler, as a feed additive for livestock, creating artwork, drawing on blackboards, fire resistant, gymnasts, athletes and mountain climbers use for grip, in aquifers, soil conditioner, to ignite fire, used as a filter medium, used as an insecticide, whiting material in toothpaste, paint and paper and that of Granite are curling, gemstone, laboratory bench tops, tombstones, used in aquariums.
