Pantellerite and Diatomite


Definition

Definition
Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth   
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite

Formation

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.   
Pantellerite 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 Pantellerite Properties

Know all about Diatomite and Pantellerite properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite belongs to Sedimentary Rocks while Pantellerite belongs to Igneous Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Pantellerite is Eutaxitic. Diatomite appears Soft and Pantellerite appears Layered and Foliated. The luster of Diatomite is dull while that of Pantellerite is earthy. Diatomite is available in grey, white, yellow colors whereas Pantellerite is available in dark greenish - grey colors. The commercial uses of Diatomite and Pantellerite 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.
