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.
Jasperoid is a rare and peculiar type of metasomatic alteration of rocks. It is formed by extreme alteration of wall rocks within a shear zone which may occur in sediments, andesites, trachytes and basalts.

All about Diatomite and Jasperoid Properties
Know all about Diatomite and Jasperoid properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite and Jasperoid belong to Sedimentary Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Jasperoid is Earthy. Diatomite appears Soft and Jasperoid appears Glassy or Pearly. The luster of Diatomite is dull while that of Jasperoid is vitreous and pearly. Diatomite is available in grey, white, yellow colors whereas Jasperoid is available in black, brown, colourless, green, grey, pink, white 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 Jasperoid are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
