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.
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.

All about Carbonatite and Jaspillite Properties
Know all about Carbonatite and Jaspillite properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite belongs to Igneous Rocks while Jaspillite belongs to Sedimentary Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Jaspillite is Banded, Trellis. Carbonatite appears Dull, Banded and Foilated and Jaspillite appears Banded and Glassy. The luster of Carbonatite is subvitreous to dull while that of Jaspillite is earthy. Carbonatite is available in black, brown, green, grey, pink, white colors whereas Jaspillite is available in red, reddish brown colors. The commercial uses of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux and that of Jaspillite are creating artwork, jewelry.
