Meaning and Definition
A rare, igneous rock primarily composed of carbonate minerals such as calcite or dolomite.
In geology and petrology, it refers to intrusive or extrusive carbonate-rich rocks of igneous origin, often associated with rare earth element deposits and forming distinctive geological structures.

FAQ
Frequently Asked Questions
No. While both contain carbonate minerals, limestone is a sedimentary rock formed from biological or chemical processes, whereas carbonatite is an igneous rock formed from cooling magma.
Carbonatite deposits are economically significant as primary sources of rare earth elements, niobium, and phosphate, which are critical for modern technology.
They are very rare on Earth's surface, representing less than 1% of all igneous rocks. Most are found in ancient continental crust.
Yes. There are rare active carbonatite volcanoes, such as Ol Doinyo Lengai in Tanzania, which erupts low-temperature, black carbonate lava.
