Description:
Methane flux measurements from surface gas manifestations and springs at the Ciomadu post-volcanic area are reported. These data contribute to extend the Romanian data-set on geological emissions of greenhouse gas to the atmosphere. A total of 46 sites were investigated for methane flux, dissolved methane content and stable carbon isotopic ratio of methane. Total methane output is in the order of 102-103 kg/year, comparable to other ancient volcanic systems in Europe. Methane is mainly abiotic in origin, variably mixed with biotic thermogenic components, likely depending on the amount of crustal sediments involved in the volcanic plumbing system
