Breccia and Carbonatite
Definition
Definition
Breccia is a rock consisting of angular fragments of stones which are cemented by finer calcareous material

Formation
Formation
Breccia is a clastic sedimentary rock which is composed of broken fragments of minerals or rock which are cemented together by a fine-grained matrix and it forms where broken, angular fragments of rock or mineral debris accumulate.
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 Breccia and Carbonatite Properties
Know all about Breccia and Carbonatite properties here. All properties of rocks are important as they define the type of rock and its application. Breccia belongs to Sedimentary Rocks while Carbonatite belongs to Igneous Rocks.Texture of Breccia is Brecciated, Clastic whereas that of Carbonatite is Granular, Poikiloblastic. Breccia appears Layered, Banded, Veined and Shiny and Carbonatite appears Dull, Banded and Foilated. The luster of Breccia is dull to pearly while that of Carbonatite is subvitreous to dull. Breccia is available in beige, black, blue, brown, buff, green, grey, orange, pink, purple, red, rust, white, yellow colors whereas Carbonatite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Breccia are creating artwork, gemstone, jewelry and that of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux.
