Mineral dust records distant from dust sources are crucial in establishing wider atmospheric dust loads in the past. However, detailed, independent chronologies for loess-palaeosol sequences distant from local dust sources are still rare in Europe. In this study we present a high-resolution OSL and pIRIR₂₉₀ chronology and multi-proxy investigation of the Irig loess-palaeosol sequence (LPS), Vojvodina, Serbia. Our results show that 4–11 μm quartz is a reliable dosimeter only up to ~59 ka (179 Gy), after which the OSL ages underestimate the expected ages based on stratigraphy. The pIRIR₂₉₀ signal displays generally good luminescence behaviour and resultant ages show good agreement with the expected stratigraphic ages, although with apparent 15 kyr and 35 kyr age underestimations at the L2-S2 and S2-L3 boundaries, respectively. The calculated dust mass accumulation rates (MAR) reveal large fluctuations during the last two glacial-interglacial cycles. During the penultimate glacial, the highest MARs were observed between 171 and 181 ka, subsequently decreasing rapidly during MIS 5. During the last glacial period, dust MARs display maximum values during MIS 2 and MIS 4, while the lowest dust input was observed during the Holocene, followed by MIS 3. Dust MAR and grain-size shifts appear to lead changes in magnetic susceptibility by several kyr. Our results imply that changes in dust availability and wind dynamics occurred prior to changes in climate-controlled soil moisture conditions at the Irig LPS. Moreover, our results reveal a close coupling of the dust MAR and grain-size variations during the Mid-Late Pleistocene. These patterns suggest that the Irig site is likely representative of regional dust dynamics, which separates it from more source proximal loess sites, such as those close to major rivers, which are likely more affected by local dust availability and river discharge.

远离尘埃源的矿物尘埃记录对于过去建立更广泛的大气尘埃负荷至关重要。然而，远离当地尘埃源的黄土-古土壤序列的详细、独立的年代学在欧洲仍然很少见。在这项研究中，我们对塞尔维亚伏伊伏丁那的 Irig 黄土-古土壤序列 (LPS) 进行了高分辨率 OSL 和 pIRIR ₂₉₀年表和多代理调查。我们的结果表明，4-11 μm 石英是一种可靠的剂量计，仅高达 ~59 ka (179 Gy)，之后 OSL 年龄低估了基于地层学的预期年龄。PIRIR ₂₉₀信号通常显示出良好的发光行为，所得年龄与预期的地层年龄非常吻合，尽管在 L2-S2 和 S2-L3 边界处明显低估了 15 kyr 和 35 kyr 年龄。计算出的尘埃质量积累率（MAR）揭示了过去两个冰期-间冰期循环中的巨大波动。在倒数第二个冰期，在 171 和 181 ka 之间观察到最高 MAR，随后在 MIS 5 期间迅速下降。在最后一个冰期，尘埃 MAR 在 MIS 2 和 MIS 4 期间显示最大值，而在 MIS 4 期间观察到最低的尘埃输入全新世，其次是 MIS 3。尘埃 MAR 和晶粒尺寸变化似乎导致磁化率变化数 kyr。我们的研究结果表明，灰尘可用性和风动力学的变化发生在 Irig LPS 气候控制的土壤湿度条件发生变化之前。此外，我们的结果揭示了更新世中晚期尘埃 MAR 和粒度变化的密切耦合。这些模式表明，Irig 场地可能代表区域沙尘动态，这将其与更多来源的近端黄土场地区分开来，例如靠近主要河流的场地，这些场地可能更受当地灰尘可用性和河流排放的影响。
