Definition

Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth

Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

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.

Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

All about Diatomite and Boninite Properties

Know all about Diatomite and Boninite properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite belongs to Sedimentary Rocks while Boninite belongs to Igneous Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Boninite is Aphanitic to Porphyritic. Diatomite appears Soft and Boninite appears Dull and Soft. The luster of Diatomite is dull while that of Boninite is vitreous. Diatomite is available in grey, white, yellow colors whereas Boninite is available in bluish - grey, brown, green, 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 Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo).
