Loess-paleosol sequences in the Vojvodina region (Serbia), located in the confluence area of the rivers Danube, Sava and Tisza, are thought to be among the oldest and most complete terrestrial paleoclimatic records in SE Europe. The Mošorin (Veliki surduk exposure) loess record in the north of the Titel loess plateau, represents a unique archive of Pleistocene climate variability, characterized by considerable high sedimentation rates during the last three glacial cycles. This study presents paleopedogenic parameters obtained from samples taken at 5 intervals from the upper 34 m of the Mošorin loess record. For the total number of 732 samples colors were determined. Wet as well as dry colors were observed using Munsell Soil Color Chart. Rubification and melanization indices were calculated following Harden (1982), using spreadsheet developed by Taylor (1988). As Kubiena (1970) define rubification, this soil development index show the degree of soil reddening relative to parent material, and melanization expresses soil darkening. As it was observed at other Euroasian loess deposits, at Mošorin loess-paleosol sequence rubification and melanization values for loess layers meet the expected results. The rubification values are significantly lower then those for paleosols. Melanization indices are much lower for paleosols. Rubification values are increasing with depth and time, while the ones for melanization decrease. This can be explained by increasing mineral weathering, nature of soil formation processes and quality of soil organic mater, although it could be related to geochemical composition of material. The results, conducted from paleopedogenic and geochemical parameters will give a better perspective on paleoclimatic transitions in Vojvodina region during Pleistocene.
