Geochemical Signature of Magmatic-Hydrothermal Fluids Exsolved from the Beauvoir Rare-Metal Granite (Massif Central, France): Insights from LA-ICPMS Analysis of Primary Fluid Inclusions

Figure 6

Microphotographs showing the different types of fluid inclusions. Detailed description of each fluid inclusion type is given in the text. (a) L1-type fluid inclusion in globular quartz crystal from the Beauvoir granite. (b) V2-type fluid inclusion disseminated in globular quartz from the Beauvoir granite. (c) L2-type fluid inclusion from a globular quartz crystal in the Beauvoir granite. (d) V2-type fluid inclusion isolated in the limpid quartz (Q2) from the La Bosse stockwork. (e) L2-type fluid inclusion in limpid quartz (Q2) from the La Bosse stockwork. (f) L3-type fluid inclusion disseminated in limpid quartz (Q2) from the La Bosse stockwork. Hl: halite; : liquid aqueous phase; Qtz: quartz; Slv: sylvite; V: vapour phase.
