At few sites with complex fluvial stratigraphies, duplicate samples were taken and then mean values were calculated subsequently. Sediment bulk material were sampled from recent streambeds of Weiße Elster sub-catchments with a spade. GRADISTAT v9.1 for the calculation of D50 (median of grain size), D75/D25 and D75-D25 (interquartile range of grain size distribution) was used. In addition, grain size analysis from SC40 core samples were conducted using dry-sieving technique for the sand fraction and a SediGraph III 5120 (Micromeritics) for the silt and clay fraction. Subsequently, stationary XRF spectrometry (Spectro Xepos energy dispersive XRF spectrometer) was applied for analysing elemental composition of bank and streambed samples from the Weiße Elster sub-basins (111 grids) and SC40 core samples. Further, a core was recovered from the Weiße Elster floodplain and a total number of 52 geochemical samples was obtained from this SC40 core. Based on the grid, a map was created in which the primarily represented geological unit were assigned as a raster-cell parameter. The sub-catchments samples were classified according to their geological features. Thus, the extracted sediments contain the geochemical signal of the respective sub-catchment. A grid of 8*8 km cells was arranged over the entire Weiße Elster catchment. Hydro-sedimentary provenance analysis, catchment-scale approach, XRF analysis, Fluvial Geomorphology, Holocene, overbank silt-clay depositionįor XRF sediment provenance analysis in the Weiße Elster catchment of Central Germany sediment bulk material of recent streambeds from sub-catchments were sampled within a systematic mesoscale framework.
