5.1 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.

Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.

All about Carbonatite and Arkose Properties

Know all about Carbonatite and Arkose properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite belongs to Igneous Rocks while Arkose belongs to Sedimentary Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Arkose is Clastic. Carbonatite appears Dull, Banded and Foilated and Arkose appears Rough and Dull. The luster of Carbonatite is subvitreous to dull while that of Arkose is dull. Carbonatite is available in black, brown, colourless, green, grey, pink, white colors whereas Arkose is available in reddish brown colors. The commercial uses of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux and that of Arkose are in aquifers, soil conditioner, source of magnesia (mgo), tombstones.
