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.

Tuff is formed when large masses of ash and sand which are mixed with hot gases are ejected by a volcano and avalanche rapidly down its slopes.

All about Diatomite and Tuff Properties

Know all about Diatomite and Tuff properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite belongs to Sedimentary Rocks while Tuff belongs to Igneous Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Tuff is Clastic, Pyroclastic. Diatomite appears Soft and Tuff appears Dull, Vesicular and Foilated. The luster of Diatomite is dull while that of Tuff is vitreous to dull. Diatomite is available in grey, white, yellow colors whereas Tuff is available in brown, grey, yellow colors. The commercial uses of Diatomite and Tuff 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.
