| Abstract | Introduction: Understanding chemical interactions between the nearsurface atmosphere and the surface of Venus is a key for the comprehension of the planet’s atmosphere chemistry and surface mineralogy [1], [2]. However, the chemical reactivity of basaltic materials prevailing at the Venus surface versus the hot atmospheric gases is still poorly known owing to a lack of both thermodynamic and kinetic direct data. We attempted to fill this gap by experiments at controlled conditions in a model modern Venus atmosphere (dry, CO2-rich, sulfur-bearing) as well as in a humid early Venus environment using a Venusian chamber developed in Toulouse. Chemical exchanges between solids and the model atmosphere were monitored by in situ gas sampling during the experiments and high temperature and pressure, and by analyses of the solid samples after the runs. |
