Abstract
Overall, clumped isotope values of CaCO3 minerals precipitated between 23 °C and 91 °C (with and without NaCl addition) follow a line with a slope close to results from statistical thermodynamics. We conclude for calcium carbonate and hydromagnesite that the combined effect of salt ion concentration, acid fractionation and polymorphism is negligible for Clâ and Na+ with respect to clumped isotope geochemistry, but that offsets are possible in brines containing high concentrations of CaCl2.
