Definition
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals
Blueschist is a metamorphic rock which is generally blue in color and is formed under conditions of high pressure and low temperature

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.
Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.

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