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.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

All about Carbonatite and Scoria Properties
Know all about Carbonatite and Scoria properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite and Scoria belong to Igneous Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Scoria is Vesicular. Carbonatite appears Dull, Banded and Foilated and Scoria appears Glassy and Vesicular. The luster of Carbonatite and Scoria is subvitreous to dull. Carbonatite is available in black, brown, colourless, green, grey, pink, white colors whereas Scoria is available in black, brown, dark grey to black, red colors. The commercial uses of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux and that of Scoria are as a traction material on snow-covered roads, creating artwork, high-temperature insulation, in gas barbecue grills.
