| Abstract: | With the development of new technologies and the increasing demands for rare earth elements (REEs) around the world, the metallogenic mechanism of rare earth deposits has become an international research hotspot. High-temperature and high-pressure experiments on the distribution behavior of rare earth elements can provide effective constraints for studying the migration, differentiation, and deposition mechanisms of rare earth elements in the magmatic and hydrothermal systems. The experiment results provide an important theoretical basis for the understanding of geochemical behavior of rare earth elements and the mineralization processes in the REE deposits. In this paper, we summarize the recent high-temperature and high-pressure experimental knowledge advances in the distribution behavior of rare earth elements in the magmatic and hydrothermal systems, including partial melting, liquid-liquid immiscibility, fractional crystallization, fluid-melt partitioning, as well as the migration, differentiation and precipitation mechanism of rare earth elements in the hydrothermal fluids. Finally, future work that enhances our understanding of rare earth elements migration and deposition mechanisms in magmatic and hydrothermal systems are briefly proposed. |
