对来自中欧喀尔巴阡盆地的100多个碳同位素数据进行了统计分析。喀尔巴阡盆地中部的δ 13 C值呈正态分布，平均值为-5 ± 2.5‰，而斯洛伐克东北部的δ 13 C值则呈偏重值分布。δ 13 C的平均值表明碳的地幔起源，尽管该地区缺乏近期的火山活动。这与CO2排放中地幔He的存在是一致的。
More than hundred carbon isotopic data were examined statistically for the CO2 discharges from the Carpathian Basin, central Europe. The δ13C values from the central Carpathian Basin show a normal distribution with the average value of –5 ± 2.5‰, whereas those from north-eastern part of Slovakia show a distribution slightly skewed towards heavier values. The average δ13C 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.
