Abstract
The Maoniuping rare earth elements (REE) deposit, located in the Mianning — Dechang REE metallogenetic belt on the west margin of the Yangtze Craton, is related to a Himalayan carbonatite and alkalic rock association. Fluid inclusion studies revealed three types of inclusions in quartz, fluorite, calcite and barite, including melt inclusions (M type), melt-fluid inclusions (ML type) and fluid inclusions (L type). Microthermometry, SEM/EDS and LRM was performed on M type inclusions and L type inclusions in fluorite, barite and quartz. The results show that the ore-forming fluid could be derived from a carbonatite and was a high temperature, high pressure, K-rich, CO2-rich, multi-component fluid.
