Abstract : Here we report δ18O values and for the first time δD and lithium isotopic data for the Pavin crater lake (French Massif Central). In its deeper unmixed part, this meromictic lake presents low H and O isotope compositions as a result of CO2 intrusion and the presence of mineral water ingress. This influence of sub-lacustrine water contribution is confirmed by lithium isotopes with low δ7Li values.
