PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.993120 (DOI registration in progress) Abstract: The 87Sr/86Sr Holocene record presented here is based on the stalagmite SMT16 collected in São Mateus cave (13.67°S; 46.37°W) located in the Parque Estadual de Terra Ronca (PETER) in central Brazil. This data was presented in the publication by Della Libera et al. (2026). The analysis for the stalagmite 87Sr/86Sr isotope record was determined by solution-based analysis, using a multi-collector inductively coupled plasma-mass spectrometry (MC-ICP-MS) at LEGGA-UnB, and laser ablation mass spectrometry (LA-MC-ICP-MS) at Johannes Gutenberg University (JGU) Mainz (Weber et al., 2018, 2020). The solution analysis record consists of 15 data points, whereas the laser ablation consists of 87 data points. Carbonate host rock and soil samples were also analyzed using the solution-base method. Overall, the speleothem range of values lies between the soil (more radiogenic) and the carbonate host rock (less radiogenic).
