Previous correlations of loess in Europe and China have tended to focus on multi-millennial timescales, with no detailed examination of dust MAR at the two ends of the Eurasian loess belt on shorter, sub-orbital scales. Here we present a detailed quartz optically stimulated luminescence (OSL) chronology from the Serbian Titel Loess Plateau (Veliki Surduk loess core) and the Chinese Loess Plateau (Lingtai section). The luminescence ages pass internal tests and show consistent increases in age with depth, with no obvious major hiatuses. However, as reported before, it seems the quartz OSL technique is only capable of accurate age determination up to accrued doses of ca. 150 Gy (ca. 30-40 ka) due to approaching field saturation of the quartz OSL signal. Two age-depth models were used to reconstruct dust MARs, where one utilises OSL data solely and the other additionally makes assumptions about sedimentation rates. Although short-term fluctuations in MAR are model dependent, general MAR patterns between the two sites are very similar, with peak MAR occurring rather late in the last glacial (ca. 13-25 ka). This suggests that at least broad scale trends in dust activity within the last glacial period may be similar at a continental scale. (C) 2018 Elsevier Ltd and INQUA. All rights reserved.

However, despite recent progress in stratigraphic and chronometric methods, the correlation of many loess sequences is often still based on untested assumptions over loess deposition, preservation, soil type and age. As such, the aim of this overview is to provide an adequate framework for evaluation of the accuracy of loess correlations applied on different temporal and spatial scales across Eurasia. This opens up possibilities for detailed temporal and spatial environmental reconstructions across the huge loess provinces of the Eurasia and provides a framework for future extension of this to North America. Additionally, we evaluate the potential development of appropriate sub-millennial scale loess correlations, as well as essentially important chronological approaches for establishing valid correlations between different loess records, such as current improvements in tephrochronology, 14C and luminescence dating techniques.

The reliability of these records is fundamental to understand past global change. Here we use the most detailed luminescence dating age model yet published to show that the ICS chronology for the Quaternary terrestrial type section at Jingbian, desert marginal Chinese Loess Plateau, is inaccurate. There are large hiatuses and depositional changes expressed across a dynamic gully landform at the site, which demonstrates rapid environmental shifts at the East Asian desert margin. We propose a new independent age model and reconstruct monsoon climate and desert expansion/contraction for the last ~250 ka. Our record demonstrates the dominant influence of ice volume on desert expansion, dust dynamics and sediment preservation, and further shows that East Asian Summer Monsoon (EASM) variation closely matches that of ice volume, but lags insolation by ~5 ka. These observations show that the EASM at the monsoon margin does not respond directly to precessional forcing.

Indeed, the Danube River and tributaries may themselves be responsible for the transportation of large volumes of silt that ultimately drive loess formation in the middle and lower reaches of this large catchment. However, this vast loess province lacks a unified stratigraphic scheme. European loess research started in the late 17th century in the Danube Basin with the work of Count Luigi Ferdinand Marsigli. Since that time numerous investigations provided the basis for the pioneering stratigraphic framework proposed initially by Kukla (1970, 1977) in his correlations of loess with deep-sea sediments. Loess-palaeosol sequences in the middle and lower reaches of the Danube River basin were a key part of this framework and contain some of the longest and most complete continental climate records in Europe, covering more than the last million years. However, the very size of the Danube loess belt and the large number of countries it covers presents a major limiting factor in developing a unified approach that enables continental scale analysis of the deposits. Local loess-palaeosol stratigraphic schemes have been defined separately in different countries and the difficulties in correlating such schemes, which often change significantly with advances in age-dating, have limited the number of basin-wide studies. A unified basin-wide stratigraphic model would greatly alleviate these difficulties and facilitate research into the wider significance of these loess records. Therefore we review the existing stratigraphic schemes and define a new Danube Basin wide loess stratigraphy based around a synthetic type section of the Mošorin and Stari Slankamen sites in Serbia. We present a detailed comparison with the sedimentological and palaeoclimatic records preserved in sediments of the Chinese Loess Plateau, with the oxygen isotope records from deep-sea sediments, and with classic European Pleistocene stratigraphic subdivisions. The hierarchy of Danubian stratigraphic units is determined by climatically controlled environmental shifts, in a similar way to the Chinese loess stratigraphic scheme. A new unified Danube loess stratigraphic model has a number of advantages, including preventing confusion resulting from the use of multiple national schemes, a more transparent basis, and the potential to set Pleistocene palaeoenvironmental changes recorded in the Danube catchment area into a global context. The use of a very simple labelling system based on the well-established Chinese loess scheme facilitates interpretation of palaeoenvironmental information reported from the Danube Basin loess sites in a wider more accessible context that can be readily correlated world-wide. This stratigraphic approach also provides, for the first time, an appropriate framework for the development of an integrated, pan-European and potentially pan-Eurasian loess stratigraphic scheme. © 2015 Elsevier B.V.

However, the source of dust material to Greenland over the last glacial period is the subject of considerable uncertainty. Here we use new clay mineral and <10μm Sr-Nd isotopic data from a range of Northern Hemisphere loess deposits in possible source regions alongside existing isotopic data to show that these methods cannot discriminate between two competing hypothetical origins for Greenland dust: an East Asian and/or central European source. In contrast, Hf isotopes (<10μm fraction) of loess samples show considerable differences between the potential source regions. We attribute this to a first-order clay mineralogy dependence of Hf isotopic signatures in the finest silt/clay fractions, due to absence of zircons. As zircons would also be absent in Greenland dust, this provides a new way to discriminate between hypotheses for Greenland dust sources. © 2015. American Geophysical Union. All Rights Reserved.

In order to allow for correlations with other Quaternary records, reliable chronologies are needed. We therefore apply post-IR infrared (IR) stimulated luminescence (post-IR IRSL; pIRIR290) dating to the uppermost 20 m of the loess sequence at Paks. The pIRIR290 ages are compared with blue quartz OSL ages to test for potential age overestimation due to poor signal re-setting, and the observed good agreement is taken to imply that the more difficult to bleach pIRIR290 signal was reset prior to deposition. Our pIRIR290 based chronology reveals that most of the Late Pleistocene loess was deposited during marine isotope stage (MIS) 3 and during the Last Glacial Maximum (LGM). This is in disagreement with formerly published ages. The discrepancy can most likely be explained by anomalous fading (resulting in an age underestimate); this conclusion is supported by our uncorrected 'standard' IRSL ages. We further confirm that the Basaharc Double soil complex can be correlated with MIS 7; the underlying loess and soils cannot be dated accurately because the pIRIR290 signal approaches saturation. © 2013 Elsevier Ltd and INQUA.

Charcoals from the sequence made it possible to test the accuracy of 14C ages from mollusc shells. This approach revealed that 14C ages from some gastropods having small shells (<10 mm) (Succinella oblonga, Vitrea crystallina) are statistically indistinguishable from the ages of charcoals, while others (Clausiliidae sp., Chondrula tridens) show age anomalies up to 600–800 years. OSL and pIRIR@290 ages are found to be consistently older, while post-IR OSL ages are younger than the 14C ages from charcoals and molluscs by some thousands of years, except for pIRIR@225 ages that match the radiocarbon ages quite well. OSL and IRSL ages have scatters up to 7–10 thousand years within 40 ka, while charcoals and small molluscs yield consistent ages with relatively low variability. Beyond the observation that some small molluscs seem to yield reliable 14C ages, calibrated 2σ age ranges of the radiocarbon data (ca 500–800 years for 20 to 30 ka) are an order of magnitude narrower than those of the OSL/IRSL methods (1800–4000 years for 25 to 35 ka). Thus, for establishing chronologies within 40 ka, which are both accurate and precise enough to address issues like synchroneity of millennial-scale paleoenvironmental events across regions (e.g. North Atlantic and Europe), AMS radiocarbon dating of shells of specific loess molluscs and charcoals may probably be a powerful chronological tool. However, additional work is definitely required involving 14C and OSL/IRSL dates from other loess sequences to further test the performance of these two supposedly robust chronometers.

These interstadials were dated to 26,420–27,970, 23,185–24,880, and 18,810–20,770 cal BP, and correlate well with the Dansgaard-Oeschger (DO) interstadials 2 and 3 and the post LGM warm interval seen in the Greenland ice core oxygen isotope records. Intervening cold phases, on the other hand, were found between 24,880–26,420 and 20,770–23,185 cal BP, correlating with Heinrich event 2 and the LGM. These data overall confirm that millennial scale climate variability during Marine Isotope Stage 2 had profound effect on the terrestrial ecosystems in the continental interior of SE Europe, leading to periodic boreal woodland expansions and contractions and wildfires.

Loess deposits up to 20 m thick cover the Sutto travertine complex, located in the very northern part of Hungary, next to the right bank of the Danube River. The loess is intercalated with two weakly developed greyish horizons, two thinner-brownish steppe-like soils and a pedocomplex, including a reddish-brown clay-enriched horizon covered by a chernozem-like paleosol. Infrared optically stimulated luminescence (IRSL) dating was applied on polymineral fine grain material to determine the depositional age of the loess. The uppermost loess yields IRSL age estimates ranging from 15 to 40 ka. The loess on top of the pedocomplex yields IRSL age estimates ranging from 48 to 60 ka. The pedocomplex most likely correlates with the Marine Oxygen Isotope Stage (MIS) 5 interglacial period. The loess from below the pedocomplex was deposited during the penultimate glaciation, as evidenced by amino acid racemization (AAR) results. Further independent age control is provided by radiocarbon dating for the upper part of the profile and by uranium-series ((230)Th/(234)u) ages correlating the travertine below the loess with MIS 7-8. The magnetic susceptibility record through the sequence shows a strong correlation with the loess layers and soil horizons. (C) 2008 Elsevier Ltd and INQUA. All rights reserved.

Luminescence dating was carried out to establish a more reliable chronological framework for the Hungarian loess record. The lowermost palaeosol of the section, probably an equivalent of the MF2 horizon at the Mende key section, is superimposed on penultimate glacial loess. An IRSL age estimate of about 65 ka BP was determined for the lower part of this palaeosol, indicating soil formation late in oxygen isotope stage (OIS) 5 or early in OIS 3. A significant hiatus most likely occurs in the lower part of the lower fossil soil. The loess between the upper and and lower palaeosol yielded a mean luminescence age of about 50ka BP. The upper palaeosol is probably an equivalent of the MF1 horizon at the Mende type section, formed between 37 and 25ka BP, and so this palaeosol represents the Hengelo and/or Denekamp interstadial of northwestern European stratigraphy. The loess is intercalated by a humic horizon, which yielded a mean luminescence age estimate between 21 and 19 ka at the Albertirsa section. (C) 2002 Elsevier Science Ltd and INQUA.

Based on this combined luminescence dating study a new chronology is proposed for the "Young Loess" in Hungary. Luminescence dating suggests that the loess below the MF2 horizon formed during the penultimate glaciation. The MF1 horizon probably formed during an interstade within oxygen isotope stage 3. For the youngest loess, overlying MFI, a very high accumulation rate was determined. Large time gaps occur above MF2 and MF1, indicating that most of the record of the Last glaciation is missing in the standard sections at Basaharc, Mende, and Paks. Either large discontinuities or a very low accumulation rate occurred in all three type sections during the soil-forming periods. High-resolution studies of climatic proxies using this combined luminescence dating approach provide a reliable chronological framework for loess and loess derivatives of the last glacial cycle in Hungary, although a precise and complete chronostratigraphic reconstruction cannot be achieved from the incomplete records found at these sites.
