Information about Carbonatite

Rocks are naturally occurring solids which are composed of minerals & have been used by humans since ages. From Stone Age, rocks are used for various purposes. Also, the metals and minerals found in rock play an important role in our life. Get to know all the Carbonatite Uses. We have provided you with all information about Carbonatite rock here. Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals. Carbonatite is available in black, brown, green, grey, pink, white colors. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Carbonatite is white. Get to know more about Carbonatite rock and characteristics of Carbonatite rock in the next sections.
