An integrated rock-magnetic and geochemical approach to loess/paleosol sequences from Bohemia and Moravia (Czech Republic): Implications for the Upper Pleistocene paleoenvironment in central Europe

Popis výsledku v původním jazyce

Two central European loess/paleosol sequences (MIS 6-2), from central Bohemia (Zeměchy) and southern Moravia (Dobšice), situated in the important climatic transition zone between the oceanic (Atlantic) and continental climate regimes, were investigated for rockmagnetism, geochemistry, grain size and micromorphology. In both sites the magnetic profile shows good agreement with the standard model of magnetic enhancement in paleosols as established in the Chinese loess. The magnetic signal is dominated bythe presence of fine-grained magnetite and maghemite, formed in-situ and controlled by the intensity of soil formation. Magnetic proxies corresponded to proxies of chemical weathering and leaching intensity such as the Chemical Index of Alteration (CIA),the Cation Exchange Capacity (CEC) and the Rb/Sr ratio (correlation coefficient r=TILDE OPERATOR+D910.6-0.93) during the whole Lower Weichselian (MIS 5d-5a) and, in general, also during the Pleniglacial (MIS 4-2). Nevertheless, for the E
