Definition
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals
Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth

Etymology
From any intrusive igneous rock, having a majority of carbonate minerals
From Late Latin Basaltes (variant of basanites ), very hard stone, which was imported from Ancient Greek Basanites

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.
Basalt forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

All about Carbonatite and Basalt Properties
Know all about Carbonatite and Basalt properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite and Basalt belong to Igneous Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Basalt is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Carbonatite appears Dull, Banded and Foilated and Basalt appears Dull and Soft. The luster of Carbonatite is subvitreous to dull while that of Basalt is not available. Carbonatite is available in black, brown, colourless, green, grey, pink, white colors whereas Basalt is available in black, brown, light to dark grey colors. The commercial uses of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux and that of Basalt are an oil and gas reservoir, commemorative tablets, creating artwork, used in aquariums.
