Delineating the Origin of Groundwater in the Golgohar Mine Area of Iran Using Stable Isotopes of 2H and 18O and Hydrochemistry

Surface water-groundwater interaction using tritium and stable water isotopes: A case study of Middelburg, South Africa

“…Numerous processes such as dissolution, cation exchange, chemical reactions, and mineral depositions may contribute to changes in water solutes from its source. Since stable water isotopes are conservative during chemical reactions, they are used in addition to hydrochemical data in cases like these to determine water sources and flowpaths (Jahanshahi and Mohammad, 2017). They can give early warning of any potential contaminants, even if they are not yet a threat (Miljevic and Golobocanin, 2007).…”

Origin and evolution of groundwater in the Goharzamin mine area using hydro-geochemical and isotopic analyses

“…As a result, efforts have been made to determine the hydrochemical properties of groundwater seepages that fall into the Goharzamin mine pit and find the source of them. The research conducted by Jahanshahi and Zare (2017) has identified Khairabad Playa, located in the north of the Goharzamin pit (about 13 km), as the primary source of salinity. They attributed this to the excavation of the pit, which changed the hydrological conditions of the area.…”

“…Also, in Fig.14, the relationship between δ 2 H and δ 18 O for mine groundwater samples and Kheirabad Salt Lake samples (from Heidari-Nejad et al 2017) is shown. In the diagram (Fig.14), the Global Meteoric Water Line (GMWL) by the equation of δ 2 H = 8δ 18 O + 10 (Craig 1961), the East Mediterranean Meteoric Water Line (MMWL) by the relationship of δ 2 H = 8δ 18 O + 22(Gat and Carmi 1970), the Iranian Meteoric Water Line (IMWL) by the linear equation of δ 2 H = 6.89δ 18 O + 6.57(Shamsi and Kazemi 2014), and the Local Meteoric Water Line (LMWL) by the equation of δ 2 H = 7.12δ 18 O + 15.92(Jahanshahi and Zare 2017) are also plotted. The IMWL and LMWL exhibit lower vapor humidity compared to the GMWL due to their lower slope values.…”
