Cover Story: Dual isotopes of sulfate are systematically investigated to quantitatively elucidate sulfate sources and isotopic behaviors during groundwater circulation and to constrain reservoir temperatures in the Jimo nonvolcanic geothermal system, China. The results show that δ34SSO4 and δ18OSO4 values ranged from −21.0 to 5.7‰ and from 1.1 to 8.8‰, respectively. Dramatic geochemical variations are driven by oxygen isotope exchange between sulfate and water, sulfide oxidation and induced carbonate, and silicate dissolution and the mixing of shallow groundwater. These processes significantly affect geothermometric estimates, with temperature overestimations of up to 52−62% by sulfate–water oxygen isotope geothermometers. This study offers new insights into the significant impact of sulfate-related processes on geothermometric estimates, a factor often overlooked when using aqueous geothermometers. View this paper
