| contents | The data refer to the geochemical and isotopic characterization of sandstones, with carbonate cementation (beach rocks), and hybrid carbonates, formed by algal mats, in the shallow platform of the South Atlantic Ocean, Espírito Santo - Brazil. The determination of 14C activity was performed on 10 samples in Accelerator Mass Spectrometry Dating (AMS), University of California, Irvine (UCL). Sample preparation backgrounds have been subtracted based on measurements of 14C-free calcite. Radiocarbon concentrations were given as fractions of the modern standard, δ14C, and the conventional radiocarbon age followed the convention of Stuiver and Polach (1977). The 14C calibration was performed on the Radiocarbon Calibration Program* CALIB REV7.1.0, Copyright 1986-2018 (Stuiver and Reimer, 1993), with marine13.14C calibration dataset (Reimer et al., 2013). The concentrations of rare earth elements (REEs) and traces were obtained by ICP-MS (PerkinElmer Nexlon300D), after digestion according to the modified EPA Protocol 3052. The quality of data was checked by the analysis of standard reference material (PACS-2 National Research Council, Canada). |
