Despite numerous palaeoenvironmental investigations of loess–palaeosol sequences across the Carpathian Basin, well‐dated high‐resolution records are scarce. This paper presents a new high‐resolution chronology for the loess‐palaeosol sequence at Surduk (Serbia), based on optically stimulated luminescence (quartz) and post‐infrared infrared stimulated luminescence (polymineral) dating. The presented record spans 53–19 ka, with primary loess deposition occurring after 52±2 ka, and differs from previously published chronologies that relied on less precise and now superseded dating protocols. Based on the new chronology, mass accumulation rates (MARs) for Surduk were constructed and compared with sites in the Carpathian Basin. The results demonstrate that accumulation periods across this area are not consistent in timing or rates. The high‐resolution dating strategy identifies a disturbance in sediment deposition that occurred after 45±2 ka and implies that site contains a hiatus. Finally, we show samples that failed routine dose recovery and preheat plateau tests, and had low fast ratios. Supported by bulk sample geochemical analysis it is proposed that a potential abrupt source shift, during the Last Glacial Maximum, may be the cause of the anomalous luminescence behaviour.

使用新的发光年表对苏尔杜克的黄土-古土壤序列重新分析塞尔维亚后期第四纪尘埃质量积累率

尽管对喀尔巴阡盆地的黄土-古土壤序列进行了许多古环境研究，但缺乏高分辨率的高分辨率记录。本文基于光学激发发光（石英）和红外后红外激发发光（多矿物）测年，提出了Surduk（塞尔维亚）黄土古土壤序列的新高分辨率年代学。提出的记录跨度为53-19 ka，主要黄土沉积发生在52±2 ka之后，与以前出版的年代法不同，后者依赖于较不精确的现在被取代的测年协议。根据新的年代顺序，构建了Surduk的质量累积率（MARs），并将其与喀尔巴阡盆地的遗址进行了比较。结果表明，该地区的积累期在时间或速率上不一致。高分辨率测年策略确定了在45±2 ka之后发生的沉积物沉积扰动，并暗示该位点包含裂隙。最后，我们显示了常规剂量恢复和预热平稳期测试未通过的样品，其快速比率较低。在大量样品地球化学分析的支持下，建议在最后一次冰期最大值期间潜在的突然源偏移可能是导致异常发光行为的原因。
