Oxygen isotope composition of waters recorded in carbonates in strong clumped and oxygen isotopic disequilibrium Open
Paleoenvironmental reconstructions, which are mainly retrieved from oxygen isotope (δ18O) and clumped isotope (Δ47) compositions of carbonate minerals, are compromised when carbonate precipitation occurs in isotopic disequilibrium. To date…

Effects of Improved <sup>17</sup>O Correction on Interlaboratory Agreement in Clumped Isotope Calibrations, Estimates of Mineral‐Specific Offsets, and Temperature Dependence of Acid Digestion Fractionation Open
The clumped isotopic composition of carbonate‐derived CO 2 (denoted Δ 47 ) is a function of carbonate formation temperature and in natural samples can act as a recorder of paleoclimate, burial, or diagenetic conditions. The absolute abunda…

Développement du thermomètre Δ47 appliqué sur coccolithes : de la calibration en laboratoire à l’applicabilité au registre sédimentaire Open
The Δ47 geothermometer relies on the relationship between the 13C–18O abundance in carbonateand temperature of calcification. This proxy has the potential to overcome limitations of other thermometers(δ18O, Mg/Ca) to reconstruct oceanic pa…
