Archaeological Significance
Formation
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.
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.

All about Jasperoid and Diatomite Properties
Know all about Jasperoid and Diatomite properties here. All properties of rocks are important as they define the type of rock and its application. Jasperoid and Diatomite belong to Sedimentary Rocks.Texture of Jasperoid is Earthy whereas that of Diatomite is Clastic or Non-Clastic. Jasperoid appears Glassy or Pearly and Diatomite appears Soft. The luster of Jasperoid is vitreous and pearly while that of Diatomite is dull. Jasperoid is available in black, brown, green, grey, pink, white colors whereas Diatomite is available in grey, white, yellow colors. The commercial uses 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) and that 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.
