Partial pressures of the CO2 corresponding to aqueous carbonates, PCO2(W) (10-2.91-10-2.35, i.e., 0.12-0.45 vol%), and those participating in the initial dripwater formation, PCO2(H) (10-1.77-10-1.49, i.e., 1.7-3.2 vol%), were calculated from dripwater hydrogeochemistry, and compared with the partial pressure in cave air, PCO2(air) (10-3.31-10-2.49, i.e., 0.06-0.32 vol%). Both the PCO2(air) and PCO2(W) showed clear seasonal variations with maxima in summer and minima in winter. In contrast, the PCO2(H) was very stable without any significant seasonality, which could indicate its independence on surface conditions. As an exception, one anomalous drip with significantly lower and varying PCO2(W), PCO2(H), and SIcalcite was recognized as a result of prior calcite precipitation. Evolution of dripwater during CO2 degassing and calcite precipitation is demonstrated in detail in a geochemical model. The study presents new data indicating that the CO2 source might be deployed in deeper parts of karst profile (epikarst) in addition to karst soils. ER -
