A 180 ka record of environmental change at Erdut (Croatia): a new chronology for the loess-palaeosol sequence and its implications for environmental interpretation.
While there are numerous thick loess–palaeosol sequences preserved across the Carpathian Basin, well dated sites that provide terrestrial palaeoenvironmental records extending beyond last glacial–interglacial cycle are scarce. Robust chronologies are essential for correlations of loess with other long‐term Quaternary records and to further understanding ofthe palaeoenvironment and climate of this important region beyond the last 125 ka. Here a new geochronology based on 13post‐infrared infrared stimulated luminescence ages focused on the lower part of the loess–palaeosol sequence at Erdut is presented. The results show that the lower part of the Erdut profile spans the penultimate glacial cycle (MIS 7 to MIS 5). The considerable sediments overlaying the investigated part of the profile suggest that this section spans two glacial cycles, rather than the previously suggested one. The most likely source of the discrepancy is the use of uncorrected infrared stimulated luminescence signal, which can cause age underestimation if not accounted for. This study demonstrates the need to revisit sites such as Erdut, re‐date them using updated measurement protocols, and update existing palaeoenvironmental interpretations.
