In the Middle Danube Basin, Quaternary deposits are widely distributed in the Vojvodina region where they cover about 95% of the area. Major research during the last two decades has been focused on loess deposits in the Vojvodina region. During this period, loess in the Vojvodina region has become one of the most important Pleistocene European continental climatic and environmental records. Here we present the dating results of 15 samples taken from the Nosak loess‐palaeosol sequence in northeastern Serbia in order to establish a chronology over the last three glacial–interglacial cycles. We use the pIRIR290 signal of the 4–11 μm polymineral grains. The calculated ages are within the error limits partially consistent with the proposed multi‐millennial chronostratigraphy for Serbian loess. The average mass accumulation rate for the last three glacial–interglacial cycles is 265 g m−2 a−1, which is in agreement with the values of most sites in the Carpathian Basin. Our results indicate a highly variable deposition rate of loess, especially during the MIS 3 and MIS 6 stages, which is contrary to most studies conducted in Serbia where linear sedimentation rates were assumed.

塞尔维亚东北部Nosak黄土古土壤序列的IR-IRLS后年代和年代积尘速率

在多瑙河中部,第四纪沉积广泛分布于伏伊伏丁那地区,约占该地区的95%。在过去的二十年中,主要研究集中在伏伊伏丁那地区的黄土矿床。在此期间,伏伊伏丁那地区的黄土地区已成为欧洲更新世最重要的大陆气候和环境记录之一。在这里,我们介绍了从塞尔维亚东北部Nosak黄土古土壤序列中采集的15个样品的测年结果,以便建立最近三个冰期-冰间期的年代学。我们使用pIRIR 2904-11μm多矿物晶粒的信号。计算出的年龄在误差范围之内,与塞尔维亚黄土拟议的多千年年代地层学部分一致。最近三个冰间期的平均质量累积速率为265 gm -2 a -1,这与喀尔巴阡盆地大多数站点的值一致。我们的结果表明黄土的沉积速率变化很大,尤其是在MIS 3和MIS 6阶段,这与大多数在塞尔维亚假设线性沉积速率的研究相反。
