Latite and Carbonatite
Definition
Definition
Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals

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