carbonaatit
Carbonatite is a type of igneous rock that is defined by having more than 50% of its constituent mineralogy as carbonate minerals. These carbonates are typically calcite, dolomite, or ankerite. While most igneous rocks are composed of silicate minerals, carbonatites are unusual in their mineralogical composition. They can occur in various forms, including intrusive (plutonic) and extrusive (volcanic) rocks. Extrusive carbonatites are rare and are often found at specific volcanic centers.
Carbonatites are often associated with alkaline igneous rocks and are found in specific geological settings. They
Many economically important rare earth element (REE) deposits are found in or associated with carbonatites. Elements
