“…Low temperature water-rock interaction imparts measurable Zn isotope fractionation (Balistrieri et al, 2008;Bermin et al, 2006;Borrok et al, 2008;Fernandez and Borrok, 2009;Lv et al, 2016;Opfergelt et al, 2017). To date, the majority of the Zn isotope studies on surficial environments have focused on how the isotopes can trace metal contamination (Araújo et al, 2017;Bigalke et al, 2010Bigalke et al, , 2016Cloquet et al, 2008;John et al, 2008;Kelley et al, 2009;Mattielli et al, 2009;Sivry et al, 2008;Sonke et al, 2008;Wanty et al, 2013;Weiss et al, 2007).…”
