Consequently, many high-temperature applications involving diagenetic dolomites have required an assumption that the relationship between temperature and D47 in diagenetic dolomite resembles the theoretical temperature dependence for calcite. Here we present D47 results from dolomite cements for which precipitation temperatures were determined independently using fluid inclusion microthermometry. We compare a rock-based "calibration" for samples from the temperature range of similar to 73 to 176 degrees C to previously published laboratory-derived calibrations for synthetic calcites. This novel combination of approaches yields results that are broadly consistent with results reported from controlled laboratory experiments, providing an important confirmation of the utility of clumped isotopes in real-world systems. Our results suggest that the D47 of dolomite cements may provide key information in the reconstruction of burial and thermal histories and also in the recognition of potential petroleum reservoirs.
