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