The data set contains raw datafiles from PANalytical Axios mAX sequential, fully automatic wavelength-dispersive X-ray fluorescence spectrometer. The XRF data was collected in 2016 by Malvern Panalytical on 53 samples from core E-8X, with a sample spacing of ~10 cm across 6 m total core length. The attached file includes a raw data compilation of relative abundances of various oxides, and are utilised as geochemical proxies to decribe bottom water redox changes in the central North Sea during the Paleocene-Eocene Thermal Maximum.
