The surface of the archived half of the core was scanned with the ITRAX core scanner at a resolution of 1 mm, an exposure time of 1 s, and a Chromium tube at 30 kV voltage and 30 mA current at the GFZ (Potsdam) (Neugebauer et al., 2014). This X-ray fluorescence (XRF) core scanning highlights relative element intensities which can then be used to reveal sedimentary processes, although the absolute values could be influenced by down-core changes in physical properties such as grain size and water content (Neugebauer et al., 2016).
