2023-07-10 Original data of the Raman and EDXS analyses of Baideng microbial fossils in Cui et al., 2023 doi:10.57760/sciencedb.09365 en Raman spectra analyses were carried out by use of a Horiba LabRAM Odyssey Raman spectrometer. This system can provide a horizontal resolution of ~1μm and a vertical resolution of ~2μm with use of a ×100 objective. Raman spectra were excited by a 532 nm green laser with 1%–10% ND filter (ca. 0.3–3mW output power) over a ~1μm spot. Single spectrum was baseline-corrected and images of quartz, apatite and Kerogen were acquired in a 20 cm−1 broad spectral window centered at 464 cm−1, 20 cm−1 broad centered at 964 cm−1, 380 cm−1 broad centered at 1470 cm−1, respectively. Energy dispersive X-ray spectroscopy (EDXS) analyses were undertaken by an Oxford instrument X-Max 80 mm2 Silicon Drift Detector equipped on the ThermoFisher Helios G4 UC Focused Ion/Electron Dual Beam system.  research data; Raman; SEM-EDXS Linhao Cui PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset http://www.doi.org/10.1016/j.palaeo.2024.112339 Science Data Bank
