dc.description.abstractAlbite-spodumene pegmatites, which are remarkable resources of Li worldwide, may experience both magmatic-hydrothermal transition and sub-solidus hydrothermal alteration during their formation and evolution. However, fluids involved in the different stages of the evolution of a spodumene-bearing pegmatitic systems are not well defined, especially at the magmatic-hydrothermal transition stage. In the Lijiagou deposit, western Sichuan Province, fluid inclusions of a typical albite-spodumene pegmatite were studied to determine the degree of magmatic-hydrothermal fluid Li enrichment and the potential for lithium mineral crystallization at the magmatic-hydrothermal transition stage. Micro-petrographic analyses identified different types of fluid inclusions of either primary, pseudo-secondary or secondary origin and inclusions containing devitrified silicate glass. The presence of these inclusions suggests that the pegmatite underwent both the magmatic-hydrothermal transition stage and a post-crystallization hydrothermal process over its evolution. The results of fluid inclusion LA-ICP-MS analyses show that the aqueous ± carbonic fluids represented by the pseudo-secondary type 1a and 1b inclusions carry significant amount of Li, with Na and Li predominating the cation budget of these pegmatitic fluids. The aqueous ± carbonic fluids exhibit typical magmatic-hydrothermal fluid compositional characteristics and exhibit high abundance of Li in this pegmatitic system at the magmatic-hydrothermal transition stage. The relative abundance of Li to Na and K lies within the uppermost range of those reported from lithium-cesium-tantalum pegmatite systems. This is consistent with the elevated incorporation of Li in pegmatitic quartz from the albite-spodumene pegmatite. The compositional characteristics of the fluids at the magmatic-hydrothermal transition stage may be used to imply the Li mineralization potential of the pegmatitic system.en_US
