Carbonatite and Teschenite


Teschenite 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   
Teschenite is coarse- to fine-grained, dark-coloured intrusive igneous rock that usually occurs in sills, dikes and irregular masses and is always altered to some extent

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.   
Teschenite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Carbonatite and Teschenite Properties

Know all about Carbonatite and Teschenite properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite and Teschenite belong to Igneous Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Teschenite is Phaneritic. Carbonatite appears Dull, Banded and Foilated and Teschenite appears Veined and Shiny. The luster of Carbonatite is subvitreous to dull while that of Teschenite is not available. Carbonatite is available in black, brown, colourless, green, grey, pink, white colors whereas Teschenite is available in dark grey to black colors. The commercial uses of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux and that of Teschenite are cemetery markers, commemorative tablets, creating artwork, laboratory bench tops, jewelry, sea defence, tombstones.
