Ultra-High Vacuum (UHV) extraction methods for noble gases trapped in fluids inclusions

Fluid inclusions are small cavities (e.g., 10–^–3–300 µm) $\varnothing$ < 1,000 µm) found in igneous rocks (Figure 1), metamorphic, or sedimentary, which may, depending on the case, consist of one or more different phases (i.e., gas: CO₂, H₂O, N₂, etc.; liquid: CO₂, H₂O, N₂, etc.; and/or solid: NaCl, carbonate, etc.) and form during mineral crystallization, crystal overgrowth (primary inclusion), or even after the mineral has formed (secondary inclusion). The composition of gases trapped in inclusions during...
