Definition

Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals

Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks

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.

Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

All about Carbonatite and Phyllite Properties

Know all about Carbonatite and Phyllite properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite belongs to Igneous Rocks while Phyllite belongs to Metamorphic Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Phyllite is Phyllitic Sheen, Slaty. Carbonatite appears Dull, Banded and Foilated and Phyllite appears Crinkled or Wavy. The luster of Carbonatite is subvitreous to dull while that of Phyllite is phyllitic. Carbonatite is available in black, brown, green, grey, pink, white colors whereas Phyllite is available in black to grey, light greenish 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 Phyllite are cemetery markers, commemorative tablets, creating artwork, writing slates.
