摘要：
More than hundred carbon isotopic data were examined statistically for the CO2 discharges from the Carpathian Basin, central Europe. The delta(13)C values from the central Carpathian Basin show a normal distribution with the average value of -5+/-2.5 parts per thousand, whereas those from north-eastern part of Slovakia show a distribution slightly skewed towards heavier values. The average delta(13)C value indicates the mantle origin of the carbon, despite the lack of recent volcanic activity in the region. This is consistent with the existence of mantle He in the CO2 discharges.
