Archaeological Significance
Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
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 Charnockite and Diatomite Properties
Know all about Charnockite and Diatomite properties here. All properties of rocks are important as they define the type of rock and its application. Charnockite belongs to Igneous Rocks while Diatomite belongs to Sedimentary Rocks.Texture of Charnockite is Granular whereas that of Diatomite is Clastic or Non-Clastic. Charnockite appears Veined or Pebbled and Diatomite appears Soft. The luster of Charnockite is while that of Diatomite is dull. Charnockite is available in black, grey, orange, pink, white colors whereas Diatomite is available in grey, white, yellow colors. The commercial uses of Charnockite are curling, gemstone, laboratory bench tops, tombstones 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.
