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.

Icelandite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Diatomite and Icelandite Properties

Know all about Diatomite and Icelandite properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite belongs to Sedimentary Rocks while Icelandite belongs to Igneous Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Icelandite is Aphanitic to Porphyritic. Diatomite appears Soft and Icelandite appears Dull and Soft. The luster of Diatomite is dull while that of Icelandite is vitreous. Diatomite is available in grey, white, yellow colors whereas Icelandite is available in bluish - grey, grey, pink, yellow 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 Icelandite are cemetery markers, creating artwork.
