Abstract

The article provides information on the transition from carbonatitic magmas to hydrothermal brines in carbonatite systems, which are important sources of rare earth elements (REEs). The study investigates the pressure-temperature-composition properties of the Na2CO3-H2O system and shows that under high-pressure and high-temperature conditions, Na2CO3 melts transition into hydrothermal brines, leading to the enrichment of REEs in the brine-melts and the formation of economic ore bodies.
