Origin and evolution of saline groundwater in the Münsterland Cretaceous Basin, Germany: oxygen, hydrogen, and strontium isotope evidence

Integration of geological, hydrochemical and geophysical methods for prospecting thermal water resources: The case of the Hmeïma region (Central–Western Tunisia)

“…This salinity can originate from the dissolution of halite and/or infiltration of subaerial evaporated seawater (Hanor, 1987;Land et al, 1988;Iampen and Rostron, 2000). Most of the samples have ratios mNa/mCl close to unity (Table 2) indicating halite dissolution as the main source for these two elements in the groundwater (Iundt, 1971;Sadki, 1998;Grobe et al, 2000;Grobe and Machel, 2002).…”

O, H, and Sr isotope evidences of mixing processes in two geothermal fluid reservoirs at Yangbajing, Tibet, China

“…The 87 Sr/ 86 Sr isotopic ratio frequently serves as tracer for delineating recharge sources and mixing processes in cold groundwater systems (e.g. Lyons et al 1995;Neumann and Dreiss 1995;Grobe et al 2000;Négrel et al 2001; Barbieri and Morotti 2003). More importantly, the 87 Sr/ 86 Sr isotopic ratio had been also applied in hydrogeochemical studies of hydrothermal systems (Elderfield and Greaves 1981;Graham 1992;Boschetti et al 2005).…”

Use of stable isotopes to quantify flows between the Everglades and urban areas in Miami-Dade County Florida

“…Stable isotopes (d 18 O and dD) have been used extensively throughout the world to evaluate hydrometerological processes (Grobe et al, 2000;Yoshimura et al, 2001;Mikalsen and Sejrup, 2000;Noon et al, 2003;Harvey et al, 2002) and sources of water to various water bodies including aquifers (Gosselin et al, 2001;Alyamani, 2001;Criss and Davisson, 1996;Harvey and Sibray, 2001), rivers (Winston and Criss, 2003;Frederickson and Criss, 1999), lakes (Ojiambo et al, 2001;Knöller and Strauch, 2002), springs (Criss et al, 2001;Rose et al, 1996;Cartwright et al, 2000), and mines (Hazen et al, 2002). Specifically in Florida, stable isotopes have been used to evaluate the source of salinity to groundwater aquifer systems (Meyers et al, 1993;Schmerge, 2001), to evaluate seepage rates from lakes (Katz et al, 1995), sources of groundwater recharge (Price, 2001), recharge rates to aquifers (Swancar and Hutchinson, 1995;Krukikas and Giese, 1995) and the degree of evaporation experienced by surface waters (Swart et al, 1989).…”
