Geochemical normalization of magnetic susceptibility for investigation of floodplain sediments
Original language description
Magnetic susceptibility (MS) is commonly used as a proxy for industrial pollution in natural sediments or as a proxy for the percentage of detrital components in peat or carbonates. The MS may also reflect the geology of the sediment source and post-depositional processes in sediments, such as soil development. The aim of our research was to test the usefulness of Fe-normalized mass-specific MS (chi) and Ti-normalized Fe in a study of floodplain sediments. We sampled 27 floodplain sediment cores from several geologically different catchments throughout the Czech Republic, analysed their Fe and Ti concentrations using X-ray fluorescence spectroscopy, and determined their chi. To decipher sediment grain-size dependence and possible magnetic enrichment, background functions for chi were constructed using similar approach as that used for geochemical background functions of the risk element concentrations with Fe concentrations as an independent variable. It provides a mechanism to calculate chi of sediments as it would be "pristine", i.e. without post-depositional changes and pollution. Sediments derived from "mafic" source rocks had chi/Fe larger by two orders of magnitude than sediments derived from "felsic" rocks. Sediments derived from "mafic" source rocks also exhibit lower mean Fe/Ti ratio in pristine sediment strata than the average upper continental crust. The magnetic carriers inherited from mafic rocks are stepwise destroyed by pedogenesis in the floodplains and thus slowly approach chi of sediments derived from felsic rocks. Gleying processes may change chi/Fe, Fe/Ti ratio allows identifying a past action of those post-depositional processes.
