S-1 where D 0 A and D 0 C are the respective self diffusion coefficients of A and C, and Z A and Z C their respective charges. Thus if we consider a single electrolyte consisting of an anion ( A) and a cation ( C), both of them will adopt an identical diffusion coefficient D 0 AC called salt diffusion coefficient (also referred to as molecular diffusion coefficient) given by Robinson and Stokes (1959): Eq. A.2 Salt-diffusion coefficients In an electrolyte, ions adapt their diffusion coefficients to their co-diffusing ion so that the electroneutrality is always maintained. In the course of this study, the external reproducibility on SMOB was better than ☐.24 ‰ (2σ, n = 20). Bromine stable isotope composition is usually reported versus the Standard Mean Oceanic Bromide (SMOB), using the delta notation as follows: δ 81Br = ( 81Br/ 79Br) samp/( 81Br/ 79Br) SMOB − 1 x 1000, and are expressed in per mille.

Dissolved bromide (Br -) is extracted by ion exchange chromatography with NH 4NO 3 and is measured on a Neptune Plus Multicollector ICPMS in wet plasma conditions.
Bromine stable isotope composition was measured following the method fully described in Louvat et al. In the course of this study, the external reproducibility on a seawater international standard was better than ☐.1 ‰ (2σ, n = 25). Figures and Tables.Ĭhlorine stable isotope variations are usually reported versus the Standard Mean Oceanic Chloride (SMOC), using the delta notation as follows: δ 37Cl = ( 37Cl/ 35Cl) samp/( 37Cl/ 35Cl) SMOC − 1 x 1000, and are expressed in per mille. Furthermore, this study reveals gravitational fractionation as a viable process, potentially affecting other isotopic systems in various geological settings. As chloride and bromide are often conservative in groundwater systems, we highlight their essential role in unravelling the hydrodynamics and residence times of isolated aquifers. This observation reveals that these deep groundwaters have been mostly stagnant for at least 20 Myr, possibly up to 300 Myr. We show that the correlations between depth and both 37Cl/ 35Cl and 81Br/ 79Br – varying by 1.1 ‰ and 1.6 ‰ respectively – reflect the evolution toward a gravity-diffusion equilibrium of porewater in the sediment column. Here we report the first resolvable isotopic variations resulting from gravitational effects on solutes, identified on dissolved chloride (Cl -) and bromide (Br -) in a sedimentary aquifer from the Illinois Basin (USA). Yet, in a motionless and chemically homogeneous water column, dissolved isotopic substances must be distributed according to their masses.
