Supporting dataset with respect to Raman spectroscopic analysis of Palaeogene charcoals from Malcolm's Point, Isle of Mull, Scotland.

Raman spectroscopic data (raw and processed) for Palaeogene charcoal samples A1, A2, B, and A1 thin section (A1-TS), including application of FWHMRa geothermometry as per Theurer et al. (2022). Spectral data collected and processed in Renishaw WiRE 3.4 software. Those data presented in sheet 'HDHG Method 3' refer to spectral data processed in MATLAB, implementing 'peak-fit' and secondary deconvolution codes, as per O'Haver (2015, 2022) and Schito et al. (2020, 2022), respectively. O'Haver, T. (2015). A Pragmatic Introduction to Signal Processing [Online]. Retrieved from https://terpconnect.umd.edu/~toh/spectrum/CurveFittingC.html O'Haver, T.
