A synthetic fluid inclusion study of the solubility of monazite-(La) and xenotime-(Y) in H2O-Na-K-Cl-F-CO2 fluids at 800 °C and 0.5 GPa

Description

Alkali-rich F-Cl-CO2-bearing aqueous fluids are thought to be common ore-forming fluids of carbonatite-associated rare earth element (REE) deposits. Solubilities of synthetic monazite-(La) and xenotime-(Y) end-members in such fluids were determined at 800 °C and 0.5 GPa in a series of piston-cylinder experiments. At run conditions, solutions of NaCl/KCl (1.9 mol/kg) ± CO2 (5% mole), NaCl/KCl (1.7 mol/kg) ± NaF/KF (0.2 mol/kg) were trapped as synthetic fluid inclusions in quartz, and...[Show more]
