Flint and Carbonatite


Definition

Definition
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals   
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel

Formation

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.   
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.

All about Carbonatite and Flint Properties

Know all about Carbonatite and Flint properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite belongs to Igneous Rocks while Flint belongs to Sedimentary Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Flint is Banded, Rough. Carbonatite appears Dull, Banded and Foilated and Flint appears Glassy or Pearly. The luster of Carbonatite is subvitreous to dull while that of Flint is vitreous. Carbonatite is available in black, brown, colourless, green, grey, pink, white colors whereas Flint is available in black, brown, green, grey, red, white colors. The commercial uses of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux and that of Flint are creating artwork, gemstone, in fire-starting tools, manufacture of tools, metallurgical flux, jewelry, to ignite fire, used in flintlock firearms.
