Compositions of fluid inclusions from the Puy-les-Vignes deposit determined by microthermometry and Raman spectroscopy. (A–C) Homogenization temperature for the Lc-w and Lw-c hosted in quartz and wolframite as function of the CO₂ melting temperature (Tm CO₂), the clathrate melting temperature (Tm clat), and salinity. (D) Homogenization temperature for the Lw hosted in quartz as function of salinity. (E) Volatile composition of the gas phase of Lc-w and Lw-c plotted in the CO₂–CH₄–N₂ ternary diagram. (F) Bulk composition of Lc-w and Lw-c plotted in the H₂O/10–∑volatile–NaCl ternary diagram.
