New insights into uncertainties of paleoenvironmental reconstructions based on paleosol-sediment sequences - where geology meets soil science

In quaternary geology often sediments and paleosol-sediment complexes are investigated to study paleoenvironmental changes in terrestrial ecosystems. Such investigations often rely on organic and inorganic chemical properties of the investigated sequences. However, it remains questionable, to which extent post-depositional processes entail alterations of the chemical composition of paleosols and sediments. In the presentation some examples of post-depositional alterations are highlighted that are often ignored in the study of paleosol-sediment complexes. In addition, some approaches are presented to determine and quantify potential post-sedimentary alteration.
