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.
Nepheline Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

All about Diatomite and Nepheline Syenite Properties

Know all about Diatomite and Nepheline Syenite properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite belongs to Sedimentary Rocks while Nepheline Syenite belongs to Igneous Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Nepheline Syenite is Granular. Diatomite appears Soft and Nepheline Syenite appears Banded and Foilated. The luster of Diatomite is dull while that of Nepheline Syenite is greasy to dull. Diatomite is available in grey, white, yellow colors whereas Nepheline Syenite is available in brown, buff, cream, green, grey, 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 Nepheline Syenite are cemetery markers, creating artwork.
