Sažetak
As part of an ongoing multi-proxy study of the Zmajevac loess-paleosol section in Baranja in Eastern Croatia, with the purpose to reconstruct the palaeoenvironment and understand the palaeoclimate in the investigated area, detailed clay mineralogical analyses were performed using the X-ray powder diffraction (XRPD). The investigated loess- paleosol section is located on the south- western slope of the Bansko Brdo hill near the village of Zmajevac. Bansko Brdo represents an asymmetric tectonic horst built up of Miocene age basalt-andesite and volcanoclastic breccias covered with Quaternary loess-paleosol deposits [1, 2]. The about 30 m thick Zmajevac section consists of six loess horizons, five paleosols and laminated alluvial sediment. Based on the infrared stimulated luminescence (IRSL) dating results of loess from Zmajevac and in the area (e.g. [2, 3, 4]), the Zmajevac loess-paleosol section represents a detailed Penultimate and Last Glacial sedimentary record. XRPD patterns were recorded on random mounts of bulk samples and oriented mounts of the <2 µm fraction. Oriented mounts of the <2 µm fraction were record after the following treatments: a) air drying, b) saturation with K+ and Mg2+ c) ethylene-glycol solvation, d) glycerol solvation, e) heating to 400°C and 550°C. The main mineral components of the loess-paleosol are quartz, illite/muscovite, chlorite and smectite. Mixed layer illite-smectite, plagioclase, carbonate (calcite and dolomite) and kaolinite are present in a lesser quantity. In some samples negligible amount of amphiboles are present. Such mineralogical content is typical for loess. A significant increase of smectite content below the 9 m depth of the profile is observed. According to the provenance analyses based on heavy minerals associations of the silty fraction, the main sources of the material were predominantly located in the Alpine region and subordinately the Dinaride Ophiolite Zone in Bosnia [5]. A greater amount of smectite in the older horizons of loess may indicate a stronger input of local volcanic rocks during that period. [1] J. Pamić, M.
