The kind of igneous rocks with the volume fraction of carbonate mineral more than 50% is refered to carbonatite

which is temporally and spatially linked with alkaline-ultrabasic massif. This paper summarizes the discrimination features between magmatic carbonatites and sedimentary carbonate rocks

meanwhile briefly describes petrogenesis and tectonic setting of carbonatites. Since carbonatites are of great significance in exploring mantle metasomatism and diagenetic and metallogenetic processes and searching for mineral resources

this type of rock has been subject to domestic and foreign geologists.
