Carbon gas flux from the Dealul Melcului geological reserve (Corund, Romania)

Abstract

Recent studies have revealed the qualitative and quantitative importance of the free gas emanations from aqueous environments and from soil surfaces in Romania. Interesting mixing zones of different gases can be observed on the boundary between the Miocene sedimentary deposits and Late Miocene volcaniclastics. This study presents the results of investigations of free carbondioxide and methane made in Corund area (Harghita County), at Dealul Melcului geological reserve, where a presumed methane seepage was described in the past. Measurements were performed using a closed chamber method. Our observations and result show the lack of methane emanations, while the maximum value for carbon-dioxide emanation was 458 g/m2/day.
