- Аннотация: The distribution of rare-earth elements, Y, Sc and Li between aluminosilicate (L) and aluminofluoride (LF) melts in the granite system with limiting fluorine concentrations at 700 and 800°C, 1 and 2 kbar pressure was studied. The water content was from 2.5 to 50 wt.%. It is shown that all rare-earth elements, Y, Sc and Li are distributed in favor of the aluminofluoride salt melt, regardless of the experiment conditions. However, the partition coefficients of the elements KdREE(LF/L) between these phases depend on the pressure, temperature and water content in the system. It is shown for the first time that an increase in pressure from 1 to 2 kbar at T = 700-800°C in the studied system causes a significant decrease in the KdREE(LF/L). An increase in the water concentration in the system usually causes an increase in KdREE(LF/L).
