“…These temperatures are close to the solidus temperature of 550-600 ∘ C at 1 kbar for the B1 facies of the Beauvoir granite as determined experimentally [57]. The high Na/K (≥1) ratios are typical of magmatic fluids equilibrated with a granitic melt [27,28,58], whereas the low Na/Li (≤5) ratios indicate that the fluid was derived from a Li-rich magma [59]. Previous preliminary LIBS analysis on L1-type fluid inclusions found in topaz from the Beauvoir granite yielded to lower Na/Li ∼ 1-3 [29], which suggest that the very early magmatic fluid may have been even richer in Li.…”

The Beauvoir granite (Massif Central, France) represents an exceptional case in the European Variscan belt of a peraluminous raremetal granite crosscutting an early W stockwork. The latter was strongly overprinted by rare-metal magmatic-hydrothermal fluids derived from the Beauvoir granite, resulting in a massive topazification of the quartz-ferberite vein system. This work presents a complete study of primary fluid inclusions hosted in quartz and topaz from the Beauvoir granite and the metasomatized stockwork, in order to characterize the geochemical composition of the magmatic fluids exsolved during the crystallization of this evolved rare-metal peraluminous granite. Microthermometric and Raman spectrometry data show that the earliest fluid (L1) is of high temperature (500 to >600 ∘ C), high salinity (17-28 wt.% NaCl eq), and Li-rich ( e < −70 ∘ C) with Na/Li ratios ∼5. LA-ICPMS analyses of L1-type fluid inclusions reveal that the chemical composition of this magmatic-hydrothermal fluid is dominated by Na, K, Cs, and Rb, with significant concentrations (10 1 -10 4 ppm) in rare-metals (W, Nb, Ta, Sn, and Li). This study demonstrates that primary fluid inclusions preserved the pristine signature of the magmatic-hydrothermal fluids in the Beauvoir granite but also in the metasomatized W stockwork, despite the distance from the granitic cupola (>100 m) and interaction with external fluids.

“…High-temperature laboratory experiments (Burnham 1979;Candela and Piccoli 1995) and fluid-inclusion studies (Roedder 1971;Wilson et al 1980;Rankin et al 1992;Heinrich et al 1999) show that the major salt components in magmatic fluids are NaCl, KCl and FeCl 2 in comparable concentrations (up to tens of weight percent in hypersaline magmatic liquids), followed by MnCl 2 , CaCl 2 and ore metals commonly reaching concentrations of thousands of ppm to a few weight percent. Volatiles, notably CO 2 and sulphur species, also may constitute several weight percent, as indicated by CO 2 clathrates in porphyry-related and epithermal fluid inclusions Ronacher et al 2004) and by abundant sulphur in fumarolic emanations.…”

“…Applications of SXRF for the analysis of individual fluid inclusion have been previously reported by several researchers (Frantz et al, 1988;Anderson et al, 1995;Mavrogenes et al, 1995;Rankin et al, 1992;Vanko et al, 1993;Vanko and Mavrogenes, 1998). All these researches were carried out using synchrotron facilities in USA or UK.…”

Synchrotron X-ray fluorescence analyses on individual hypersaline fluid inclusions were tested to using synchrotron source at Tsukuba (KEK), Japan. The XRF instrumentation at KEK meets the purpose of fluid inclusion analysis, nondestructive, multi-element, ppm detection limits, with micro spatial resolution. In practice, however, the quantitative chemical analysis of fluid inclusion requires further considerable data accumulation. Semi-quantitative distribution of elements (mass number > 25) in single fluid inclusion was obtained.
