Definition

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

Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals

Formation

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.

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 Cataclasite and Carbonatite Properties

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