| Description | The δ13C and δ18O ratios were measured simultaneously using a triple-isotope approach developed by Loader et al. (2015), using the isotope ratio mass spectrometer (Delta V Advantage, Thermo Scientific, Germany) interfaced with a pyrolysis-type high-temperature-conversion elemental analyzer (Flash HT, Thermo Scientific, Germany), at the Institute of Geology and Geophysics, Chinese Academy of Sciences, Beijing, China. The pyrolysis temperature is set to 1350 °C. Isotope data are expressed as ‰ deviations from the VPDB and VSMOW standards. The isotope values of cellulose were determined by comparison against an in-house working standard (Merck cellulose) that was analyzed following each batch of eight samples, average analytical precision of the Merck cellulose was ± 0.05‰ for δ13C (with respect to the V-PDB standard) and ± 0.20‰ for δ18O (with respect to the V-SMOW standard). To eliminate the effect of the combustion of 13C-deficient fossil fuels, raw δ13C series were corrected by applying the method from McCarroll and Loader (2004), and the δ13C value of atmospheric CO2 was obtained from Belmecheri and Lavergne (2020).
