Karst aquifers are characterized by their heterogeneity and complex underground geometry. A great part of the world relies on karst resources for drinkable water and understanding the functioning of karst systems is essential to assess their vulnerab

The aim of this work was to understand the dynamics of CO2 in the atmosphere-soil-epikarst continuum of the Lascaux Cave site and to evaluate its impact on the hydrogeochemical signal of epikarstic waters. For these purposes, PCO2, \(\updelta^{13} {\

International audience; High and low CO2 partial pressure (Pco2) levels can induce consequences to the internal system of a karstic cave. This then can further affect the state of the cave. Subsequently, speleothem growths and the walls with prehisto
