Constraints on the hydrogeochemistry and origin of the CO2-rich mineral waters from the Eastern Carpathians – Transylvanian Basin boundary (Romania)

Carbon Gas Flux from the Dealul Melcului Geological Resereve (Corund, Romania).

“…The same author, based on isotopic composition, suggested that the Corund North gases have a deep origin possibly due to thermometamorphism of carbonates in the subsurface. The same deep origin was also suggested for the waters in the works of Kis (2013) and Italiano (2017). Our measurements revealed that the maximum free CO2 gas flux is 458.86 g/m 2 /day supporting the CO2 rich environment.…”

“…Free and dissolved gas measurements were made at other sites in Corund area as well (Kis, 2013 andPop, 2014) but these are sporadically distributed. To have a general overview about the free gas emissions and the subsurface system which feeds the emission sites, additional flux measurements are needed for the Corund area combined with isotopic compositions of the gases and of the waters.…”

Compositional measurement of gas emissions in the Eastern Carpathians (Romania) using the Multi-GAS instrument: Approach for in situ data gathering at non-volcanic areas

“…The surroundings of the volcanic range are characterized by intense, low temperature (T ~8-10 °C) gas emissions. These gas emissions appear in different manifestations, such as dry gases (mofettes) and bubbling gas, when the gas emissions interact with the local aquifers (Jánosi et al, 2011;Kis et al, 2019Kis et al, , 2020. The aquifers in this area are represented by CO2-rich sparkling mineral water, with temperature up to 22.5 °C (Berszán et al, 2009;Jánosi et al, 2011;Italiano et al, 2017).…”

Radiological investigation of natural carbonated spring waters from Eastern Carpathians, Romania

“…The water resources in this region are also accounting for 45% of the bottled mineral waters from Romania [10]. Beside drinking, the mineral waters are often associated with balneological practices [17] and is an important factor for tourism in the Eastern Carpathians [8]. Therefore, determining the radioactivity levels of these water resources is important for public health safety, and allows for the assessment of radiation exposure resulted from water ingestion.…”
