Archaeological Significance
Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Carbonatites are intrusive or extrusive igneous rocks which are defined by mineralogic composition consisting of greater than 50 percent carbonate minerals and are formed due to low degrees of partial melting of rocks.

All about Charnockite and Carbonatite Properties
Know all about Charnockite and Carbonatite properties here. All properties of rocks are important as they define the type of rock and its application. Charnockite and Carbonatite belong to Igneous Rocks.Texture of Charnockite is Granular whereas that of Carbonatite is Granular, Poikiloblastic. Charnockite appears Veined or Pebbled and Carbonatite appears Dull, Banded and Foilated. The luster of Charnockite is while that of Carbonatite is subvitreous to dull. Charnockite is available in black, grey, orange, pink, white colors whereas Carbonatite is available in black, brown, green, grey, pink, white colors. The commercial uses of Charnockite are curling, gemstone, laboratory bench tops, tombstones and that of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux.
