This paper summarizes the discrimination featuresbetween magmatic carbonatites and sedimentary carbonate rocks, meanwhile briefly describes petrogenesis and tectonicsetting of carbonatites. Since carbonatites are of great significance in exploring mantle metasomatism and diagenetic andmetallogenetic processes and searching for mineral resources, this type of rock has been subject to domestic and foreigngeologists.carbonatite; discrimination feature; mantle metasomatism; petrogenesis; tectonic setting
