Here, we applied granulometric analysis and X-ray fluorescence (XRF) analyses to study how the sedimentation at the Orlovat site was conditioned by specific geomorphological or climatic conditions. Grain-size analysis is an established method and one of the most frequently used paleoenvironmental proxies of loess deposits, and is complemented here with high resolution XRF analysis on sand-free samples to obtain a more detailed insight into paleoenvironmental conditions and weathering during the past $160 ka. The geomorphological conditions of the surrounding area and variations in wind speed over time are of great importance for a better understanding of loess–paleosol deposits. The Orlovat section was exposed to special depositional conditions, which differ from other sections studied in the Carpathian Basin. Sand was delivered during interglacials, most probably from the Deliblato Sands by the southeast Košava wind. This study highlights the importance of an integrated sedimentological approach for reliable paleoenvironmental reconstruction. Ó 2015 Published by Elsevier B.V.

The Orlovat section is a unique section in the Carpathian Basin and it is characterized by irregularities in sedimentology, magnetic susceptibility, geochemistry and other paleoproxies. Therefore the local conditions need to be understood before making claims on a regional scale. Especially the grain size distribution indicates that the Orlovat site was influenced by specific paleoenvironmental conditions. Relatively coarse grained sand was delivered during interglacials, probably from the Deliblato sands by the Košava wind. However, commonly applied methods such as grain size and rock magnetic investigations could not explain the unique situation during the MIS 3, where a paleosol is missing. Therefore, for the first time in the studies of the region, we applied high resolution X-ray fluorescence analysis to trace the changing s...

This paper presents the combination of malacological and enviromagnetic analyses, preliminary luminescence dating, litho-pedostratigraphic and palaeo-relief investigations that were applied to the Nosak loessepalaeosol sequence for the 2012 findings. The results confirm and emphasize the antiquity of the sediments preserved in the Nosak section and demonstrate the significance of the detailed and relatively complete palaeoenvironmental record they contain. These discoveries can significantly contribute to setting the background towards an improved understanding of the evolution of mammoths on the European continent.

Large areas of the basin have been intensively investigated in recent years, although deposits in the east remain largely unstudied, despite considerable regional variation in climate records. Here we discuss the sedimentary record exposed in the Orlovat brickyard using detailed litho-and pedo-stratigraphic, enviromagnetic parameters and luminescence dating. The results show an atypical Late Pleistocene succession for the Carpathian Basin. Notably, the normally widespread pedocomplex V-L1S1 is missing. This contrasts with other parts of the sequence, which appear highly resolved, such as the thicker pedocomplex V-S1 and the detailed transitions between modern pedocomplexes V-S0 and the last glacial loess unit V-L1. The luminescence chronology demonstrates a lack of intensive pedogenesis during the Early Holocene and raises an important general question about the beginning of Holocene soil formation in the region. The later Holocene soil formation adds to a growing body of evidence that suggests more complex terrestrial responses of climate to global climate change. This evidence weakens the validity of previously generalized direct stratigraphic correlations between regional terrestrial environmental archives, and global marine and ice core records.
