Description: We used stationary XRF spectrometry for analysing elemental composition of Holocene floodplain sediments from a recovered core form the Weiße Elster floodplain. For XRF sample preparation freeze-dried catchment sediments (8 g) were seaved (2mm) to discard the gravel fraction and large organic matter. Further homogenization was undertaken by grinding the samples with a vibratory Retsch mill MM 200. We created uniform pellets by pressing the powdered samples with a carbon-based binding agent in a Vaneox press at 20 t for 2 min. We conducted elemental analyses in a He atmosphere using a Spectro Xepos energy dispersive XRF spectrometer. The total drilling depth of SC40 core is 275 cm. We conducted stationary XRF measurements of 52 samples.
