Formation
Trachyandesite 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.
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.

All about Trachyandesite and Carbonatite Properties
Know all about Trachyandesite and Carbonatite properties here. All properties of rocks are important as they define the type of rock and its application. Trachyandesite and Carbonatite belong to Igneous Rocks.Texture of Trachyandesite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular whereas that of Carbonatite is Granular, Poikiloblastic. Trachyandesite appears Dull and Soft and Carbonatite appears Dull, Banded and Foilated. The luster of Trachyandesite is earthy while that of Carbonatite is subvitreous to dull. Trachyandesite is available in black, brown, light to dark grey colors whereas Carbonatite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Trachyandesite are creating artwork, pottery and that of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux.
