In this study, we present the first experimental results for stable barium (Ba) isotope ( 137 Ba/ 134 Ba) fractionation during low-temperature formation of the anhydrous double carbonate BaMn[CO 3 ] 2 . This investigation is part of an ongoing work on Ba fractionation in the natural barium cycle. Precipitation at a temperature of 21 ± 1 • C leads to an enrichment of the lighter Ba isotope described by an enrichment factor of −0.11 ± 0.06‰ in the double carbonate than in an aqueous
