Abstract
Results of thermobarogeochemical study of bastnaesite and fluorite from the Yuzhnoe and Arshan REE deposits in western Transbaikalia are presented. The minerals have been found to bear solid, primary and secondary multiphase, and gas-liquid inclusions. The studies showed that homogenization of primary gas-liquid inclusions in fluorite from carbonatites proceeded in the temperature range 370-400
