In this study, we present the first experimental results for stable barium (Ba) isotope (137Ba/134Ba) fractionation during low-temperature formation of the anhydrous double carbonate BaMn[CO3]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 barium-manganese(II…

Barium isotope fractionation during witherite (BaCO3) dissolution, precipitation and at equilibrium
Oxygen isotope fractionation in double carbonates
TLDR
The calculations suggest that the double carbonates of calcite structure are systematically enriched in 18O relative to those of aragonite and mixture structures, which provides insights into the effects of crystal structure and exchange kinetics on oxygen isotope partitioning indouble carbonates.
Barium isotope fractionation during the experimental transformation of aragonite to witherite and of gypsum to barite, and the effect of ion (de)solvation
TLDR
The magnitude of isotope fractionation is within the range of recent reports for witherite and barite formation, as well as trace Ba incorporation into orthorhombic aragonite, and no substantial impact of temperature can be found between 4 and 80 °C.
Calcium isotope fractionation during mineral precipitation from aqueous solution
Calcium isotopes are fractionated during inorganic precipitation from aqueous solutions according to their relative mass differences. The magnitude and sign of isotope fractionation depend on the…
Accurate determination of barium isotopic compositions in sequentially leached phases from carbonates by double spike-thermal ionization mass spectrometry (DS-TIMS).
TLDR
It is shown that a considerable range of Ba concentrations can be associated with the four operationally-defined sequential leaching fractions and significant variations of δ137/134Ba in the analyzed leachates suggest a considerable Ba isotope fractionation between carbonate mineral phase and non-carbonate phases of marine carbonate rocks.

A model of the Ba geochemical cycle in the ocean is discussed based on a few own and published data. Barium ion reacts with the sulfate ion in various fluids (pore water, gas–liquid and…
