| contents | The data refer to the geochemical and isotopic characterization of microbial carbonate in the shallow platform of the South Atlantic Ocean, Espírito Santo - Brazil. Carbon and oxygen isotope analysis fractions (δ¹³C and δ¹⁸O) were measured on six carbonate laminate samples using isotope ratio mass spectrometry (IRMS) on a Thermo Fisher Scientific Delta V Advantage instrument. Approximately 0,4-0,6 mg of carbonate was reacted with 100% phosphoric acid at 72ºC to release CO2 gas. International standards (NBS18, NBS19, IAEA-CO-1, IAEA-CO-8, IAEA-CO-9, and IAEA-603) were used for calibration. The analytical precision for δ13C and δ18O was better than 0,01% and 0,25%, respectively. Isotopic values are reported in delta notation (‰) relative to the Vienna Pee Dee Belemnite (VPDB) standard. |
