Sample aliquots of 100 to 200 μg were prepared with a microsampler (Sherline, model 5400) with a sampling resolution of 0.4 mm. Analyses were performed on a Thermo Finnigan Delta Plus Advantage IRMS fitted with a Finnigan Gas-Bench II automatic sample preparation system at the Stable Isotope Laboratory at the Institute of Geoscience of the University of São Paulo (Brazil). Isotope values are reported as δ13Cc and δ18Oc in ‰ relative to VPDB, with standard reproducibility (1σ) better than 0.1 ‰ in both cases. The final isotope profile after the cleanup of erroneous values comprises 933 data points for δ18Oc and 933 for δ13Cc.-44.28-19.5BrazilEuropean Research Councilhttps://doi.org/10.13039/501100000781101001957Fluid Inclusion Microthermometry in SpeleothemsNational Natural Science Foundation of Chinahttps://doi.org/10.13039/50110000180942261144753Rio de Janeiro State Universityhttps://doi.org/10.13039/501100006702E-26211.352-2021São Paulo Research Foundationhttps://doi.org/10.13039/5011000018072020/09258-4São Paulo Research Foundationhttps://doi.org/10.13039/5011000018072022/08359-7NSFC - PFPMCGSão Paulo Research Foundationhttps://doi.org/10.13039/5011000018072023/04580-3
