  "abstract": "Venus’ surface chemistry and mineralogy remain poorly constrained. Understanding surface–atmosphere interactions under a simulated Venus environment can be used to predict Venus’s surface composition and its past and current volatile cycles. This includes identifying minerals that could provide evidence for past or subsurface water. We exposed six rock-forming minerals in the Glenn Extreme Environment Rig (GEER) to simulated Venusian conditions. Magnesite formed from brucite by dehydration and carbonization. Phlogopite and muscovite reacted with HF to form fluorophlogopite and fluoromuscovite, respectively, which demonstrates in situ OH-F substitution under simulated Venusian conditions. Since fluorine substitution can increase the thermal stability of micas, this reaction may help preserve hydrous minerals that formed during an earlier, water-rich period of Venus’ history. Assuming Earth-like volcanic outgassing rates and no removal mechanisms since Venus’ last major resurfacing (∼500 Mya), SO ₂ and HF abundances could increase by several percent. Our experimental results and thermodynamic analyses reaffirm continuous emplacement of fresh volcanic material and sustained outgassing of volcanic gas to maintain the current atmospheric abundances. Identifying magnesite and fluoro-micas on the surface of Venus could provide indicators about current volatile cycles and Venus’ past geological and atmospheric evolution.",
