英文摘要Sulfate is a common and important component in the mineralizing fluids of some world-class rare earth element (REE) deposits. However, the roles of sulfate during the transport and mineralization of REEs remain unclear and need further investigation. In this study, liquid-liquid immiscibility is proposed to be a potential mechanism for the enrichment of REE in hydrothermal fluids based on a series of experiments. REEs were considerably concentrated into the separated dense liquid phase, whereas the remaining light liquid phase was depleted in REEs. In situRaman spectroscopic analyses characterized more complicated REE3+-SO42- complexes and some bisulfate species in addition to the documented REESO4+ and REE(SO4)(2)(-); the newly proposed sulfate species can transport one third of the total REEs at >200 degrees C. Therefore, the transport capacity of sulfate was underestimated in previous studies. Overall, the presence of sulfate can significantly fertilize the REE-mineralizing fluids. (C) 2021 Elsevier B.V.
