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.
Benmoreite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Diatomite and Benmoreite Properties
Know all about Diatomite and Benmoreite properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite belongs to Sedimentary Rocks while Benmoreite belongs to Igneous Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Benmoreite is Glassy, Massive, Porphyritic, Scoriaceous, Trachytic, Vesicular. Diatomite appears Soft and Benmoreite appears Rough and Dull. The luster of Diatomite is dull while that of Benmoreite is earthy. Diatomite is available in grey, white, yellow colors whereas Benmoreite is available in black, brown, light to dark grey 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 Benmoreite are commemorative tablets, creating artwork, curling.
