Normalized element ratios of sediment core LVL15-4 from Lake Vouliagmeni, Greece


The XRF core scanning for the elements Si, S, Cl, K, Ca, Ti, Mn, Fe, Br, and Sr was performed with an ITRAX core scanner equipped with a chromium X-ray tube at 200 μm step size, 30 kV tube voltage, 30 mA tube current, and a counting time of 10 s. To minimize sample-geometry effects related to differences in water content, surface irregularities, and sediment density, raw-element intensities (cps) were normalized by center-log-ratio (CLR) transformation.
