Archaeological Significance
Formation
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.
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 Carbonatite and Jasperoid Properties
Know all about Carbonatite and Jasperoid properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite belongs to Igneous Rocks while Jasperoid belongs to Sedimentary Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Jasperoid is Earthy. Carbonatite appears Dull, Banded and Foilated and Jasperoid appears Glassy or Pearly. The luster of Carbonatite is subvitreous to dull while that of Jasperoid is vitreous and pearly. Carbonatite and Jasperoid are available in black, brown, green, grey, pink, white colors. The commercial uses of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux 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).
