Archaeological Significance
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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

All about Diatomite and Jadeitite Properties
Know all about Diatomite and Jadeitite properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite belongs to Sedimentary Rocks while Jadeitite belongs to Metamorphic Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Jadeitite is Earthy. Diatomite appears Soft and Jadeitite appears Rough and Dull. The luster of Diatomite is dull while that of Jadeitite is waxy and dull. Diatomite is available in grey, white, yellow colors whereas Jadeitite is available in black, brown, green, grey, 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 Jadeitite are commemorative tablets, creating artwork, jewelry.
