Regional and Tectonic Applications of Gas/Fluid Geochemistry

Origins of gas discharging from the Qiangtang Basin in the northern Qinghai–Tibet Plateau, China: Evidence from gas compositions, helium, and carbon isotopes

“…Geochemical studies of discharging gases, including measuring gas species, concentrations, and isotopic compositions, play a significant role in the exploration of hydrocarbon and gas hydrate, in monitoring tectonic and magmatic activities, and in the environmental effect assessment of greenhouse gases (Bräuer et al, 2009;Etiope and Klusman, 2002;Yang, 2008Yang, , 2013Yang et al, 2010). The analysis of carbon isotopes is one of the most direct and effective ways to fingerprint the origin of emitting gases.…”
