Non-magnetic indicators of pedogenesis related to loess magnetic enhancement and depletion: examples from the Czech Republic and southern Siberia

Popis výsledku v původním jazyce

We carried out a multiparameter investigation for non-magnetic proxies of the intensity of pedogenesis in loess/paleosol sections from two different climate settings of central Europe and southern Siberia with the aim to clarify the problem of two opposite scenarios of magnetic susceptibility (MS) patterns. Weathering intensity can be effectively characterized by diffuse reflectance spectroscopy (DRS) and geochemical (CEC and Rb/Sr) proxies. The MS is strongly dependent on the type of soil but the geochemical proxies proved to be relatively independent of the soil type. These parameters are less affected by region-specific conditions than the MS signal. In general, no single universal proxy of weathering or pedogenesis intensity would be applicable across broad regions or considerable climatic gradients. Palaeoclimatologic interpretations of large regions should always be based on a carefully designed, multi-proxy approach.
