| Zusammenfassung |
| In our study we provide the first high resolution CO2 flux data in the youngest volcanic region of the Eastern-Central Europe, Carpathian-Pannonian Region and estimate the CO2 emission of the seemingly inactive Ciomadul volcanic complex. Our estimate includes data from focused emissions and diffuse CO2 emissions from soil. The CO2 fluxes of focused emissions range between 277 and 8172 g d-1, corresponding to a CO2 output into the atmosphere between 0.1 and 2.98 tons per year. The investigated areas for diffuse soil gas emissions were characterized by wide range of CO2 flux values, at Apor Baths, ranging from 1.7 to 82000 g m-2 d-1, while at Lăzărești ranging between 1.43 and 38000 g m-2 d-1. The highest CO2 focused gas fluxes at Ciomadul were found at the periphery of the youngest volcanic complex, which could be explained either by tectonic control across the brittle older volcanoes or by degassing from a deeper crustal zone resulting in CO2 flux at the periphery of the supposed melt-bearing magma body beneath Ciomadul. The estimate of the total CO2 output in the area is 8700 t y-1, and it is consistent with other volcanoes with similar age in Italy and USA. Taking into account the isotopic composition of the gases that indicate magmatic component, the CO2 emissions yield further support that Ciomadul may be considered a dormant volcano or PAMS (volcanoes with potentially active magma storage) rather than inactive and emphasize that CO2 output of such volcanic systems has to be accounted in the estimation of the global volcanic CO2 budget. |
