Definition
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals
Cataclasite is a type of cataclastic rock that is formed by fracturing and comminution during faulting. It is normally cohesive and non-foliated, consisting of angular clasts in a finer-grained matrix

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.
Cataclasiste rocks mainly form by pressure deep under the Earth's surface, from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

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