Complex geomorphological, geological, paleopedological and chronometrical investigations were started to reveal the development of the alluvial section and the loess/paleosol sequence containing remnants of a Late Palaeolithic site near Ver艖ce, Hungary. Different paleoenvironments were identified in the profiles of the abandoned brickyard influenced by different facies in the margin of fluvial-alluvial (Palaeo-Danube) and proluvial (southeast pediment of B枚rzs枚ny Mountain) area and the environments affected by the climate fluctuation of Late Pleistocene (loess/paleosol sequence overlying the base of alluvial materials). Sediments possibly deposited by Palaeo-Danube were identified in a basal section of the abandoned brickyard. The alluvial facies was indicated by sand, silt, and clay layers in the sediment sequence. Some parts of the alluvial sediments were covered by loess in the glacial periods intercalated by four paleosol horizons formed during interglacial or interstadial periods. The sedimentation of loess and the forming of paleosols were finished by pedimentation processes (sheet wash, redeposition) indicated by the fine layered material at the top of each paleosol horizon. Another complex fluvial-alluvial section was identified at a different part of the brickyard possibly developed synchronous with the loess/paleosol sequence during the Late Pleistocene. Based on relative and chronometrical dating methods (e.g. archaeological stratigraphy and correlation of the artifacts, 14C and luminescence dating), the development of the loess/paleosol sequence started in marine isotope stage 6 (MIS6) and the youngest layer dated to MIS2.
