Definition
Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth
Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism

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.
Greenschist is medium grade metamorphic rock, formed by the metamorphosis of mudstone or shale, or some types of igneous rock, when it is subjected to higher temperatures and pressures.

All about Diatomite and Greenschist Properties
Know all about Diatomite and Greenschist properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite belongs to Sedimentary Rocks while Greenschist belongs to Metamorphic Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Greenschist is Foliated, Platy. Diatomite appears Soft and Greenschist appears Layered and Shiny. The luster of Diatomite is dull while that of Greenschist is shiny. Diatomite is available in grey, white, yellow colors whereas Greenschist is available in dark greenish - grey, green 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 Greenschist are blackboards, manufacture of tools, writing slates.
