Supplementary Information for "Temperature dependence of clumped isotopes (∆47) in aragonite" Vrije Universiteit Brussel
"Key Points: - Precise control on carbonate formation temperatures enables more accurate clumped isotope-temperature calibrations - Isotopic ordering and acid fractionation in aragonite have a similar temperature dependence as in calcite, enabling combined calibrations - The Δ47- relation in carbonates is non-linear, including hot calibration data offsets the calibration in the cold temperature range Abstract Clumped isotope thermometry can independently constrain the formation temperatures of carbonates, but a lack of precisely temperature-controlled calibration samples limits its ...
