Charcoal 14C ages are found to be protocol-dependent, with ages obtained from the high temperature (800 °C) fraction of the two-step combustion (TSC) protocol being always the oldest and likely most reliable. One step combustion (OSC) at 1000 °C produces comparable ages with those obtained from the low temperature (400 °C) fraction of the TSC protocol. Discrepancies between the ABA-TSC400 and TSC800 ages become larger for older, and less well-preserved charcoal fragments. Testing of shell ages against those of charcoals reveals that Succineidae sp., Chondrula tridens, Trochulus hispidus and members of the family Clausiliidae yield 14C ages that are statistically indistinguishable from charcoals recovered from the same stratigraphic interval, or with the ABA-TSC800 charcoal age. Thus, these species show great potential for creating accurate and precise chronologies for loess records within the useful range (<~40 ka) of 14C-dating of land snails. Conservative estimates of 95% uncertainties of the resulting Bayesian age-depth models are in the range of 500-800 yr. However, these uncertainties are strongly dependent on the number of dates available and the resolution of sampling, but they are usually well below those of luminescence chronologies. © 2016 Elsevier B.V.

AB - Loess deposits are recorders of aeolian activity during past glaciations. Since the size distribution of loess deposits depends on distance to the dust source, and environmental conditions at the source, during transport, and at deposition, loess particle size distributions and derived statistical measures are widely used proxies in Quaternary paleoenvironmental studies. However, the interpretation of these proxies often only considers dust transport processes. To move beyond such overly simplistic proxy interpretations, and toward proxy interpretations that consider the range of environmental processes that determine loess particle size distribution variations we provide a comprehensive review on the physics of dust particle mobilization and deposition. Furthermore, using high-resolution bulk loess and quartz grain size datasets from a last glacial/interglacial sequence, we show that, because grain size distributions are affected by multiple, often stochastic processes, changes in these distributions over time allow multiple interpretations for the driving processes. Consequently, simplistic interpretations of proxy variations in terms of only one factor (e.g. wind speed) are likely to be inaccurate. Nonetheless using loess proxies to understand temporal changes in the dust cycle and environmental parameters requires (i) a careful site selection, to minimize the effects of topography and source distance, and (ii) the joint use of bulk and quartz grain size proxies, together with high resolution mass accumulation rate calculations if possible. © 2016 Elsevier B.V.

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.

The present work reports a high-resolution SAR-OSL chronology for the L1 (MIS 2-4), S1 (MIS 5) and L2 (MIS 6) units of the loess-palaeosol profile from Costineşti, that contains at least five loess-palaeosol alternations and is located on the Black Sea Shore (Dobrogea, SE Romania). Analysis were performed on fine (4-11μm) and coarse (63-90μm) quartz grains extracted from 25 samples collected at very high resolution (10-20cm). Luminescence investigations confirm the reliability of the SAR-OSL dating protocol previously applied to Romanian loess (preheat at 220°C for 10s, cutheat to 180°C and elevated temperature OSL (ETOSL). The dose-response curve is best described by the sum of two saturating exponential functions. The results confirm the different saturation characteristics of fine and coarse grains of quartz, as reported in previous studies on loess sections in SE Romania. The equivalent doses obtained for coarse grains are higher than those obtained for fine grains, for all samples. The fine quartz OSL age estimates are significantly younger than the coarse quartz age results, as in the case of previous studies on the Mircea-Vodǎ and Mostiştea loess sections. Coarse quartz in samples collected from the upper part of S1 yielded ages of 94±11ka, 116±11ka and 120±10ka that do not seem to underestimate the true burial age. The same observation applies to the upper part of L2. Overall, from the luminescence results it can be concluded that the S1 palaeosol formed during the MIS 5, and the discrepancy observed on coarse and fine quartz OSL ages is a general feature of SE Romanian loess. © 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.

An analysis of the OSL dose response in the high dose region (5 kGy) was performed and the response is well represented by a sum of two saturating exponential functions. The saturation characteristics of the fine-grained (4-11 μm) quartz were found to be much higher than the saturation characteristic doses of the coarser material (63-90-125-180 μm). The equivalent doses have been determined by interpolating on the region of the dose response growth curves where the first exponential component was not fully saturated. Optical ages ranging from 38.5 ± 2.8 ka (4-11 μm) to 44.6 ± 3.8 ka (90-125 μm) were obtained for the underlying sand layer, whereas for the overlying loess, 36.2 ± 3.3 ka (125-180 μm) to 44.4 ± 3.4 ka (4-11 μm) values were found. The luminescence ages yielded by each grain-size fraction analyzed are consistent within errors limits. The weighted average ages obtained on the two samples confirm chronologically (alongside volcanic glass chemical data) the correlation of this ash layer with the Campanian Ignimbrite/Y5 tephra. These new chronological results establish the value of this ash layer as one the most important stratigraphic markers for the terrestrial deposits of the Lower Danube region during Marine Isotope Stage 3. © 2012 Elsevier B.V.

AB - The literature dealing with secondary carbonates in loess-paleosoil sequences is in many cases ambiguous, which means that different concepts are used for the same features, whereas certain concepts referring to different types are used as collective nouns. The aim of this study is to give a review on this nomenclature and to draw comparision between the various types and concepts. As a main guiding principle the article of Becze-Deák et al. (1997) is used, because it has formulated a proposition of a nomenclature which would be worthwhile to adopt. The terms and concepts introduced by their work are exact, referring to certain separated secondary carbonates and are of decisive importance with a view to paleoenvironmental reconstruction. The research of secondary carbonates in loess-paleosoil sequences is of great importance, through providing detailed information on the paleoenvironment, especially on the former moisture conditions (including leaching processes). Secondary carbonates originate from the vertical, horizontal or in situ resettlement of carbonates during pedogenesis in the soil-sedimentary environment. Among others, calcified root cells, hypocoatings and needle-fiber calcite are classified into the microscale category, while concretions (e.g. loess dolls) belong to the macroscale types.

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.

The older Bag Tephra has been described From numerous loess outcrops in Hungary, whereas the younger Paks Tephra has been described only from the brickyard of Paks, in southern Hungary. The most characteristic heavy minerals in these horizons are various clinopyroxenes occurring in different proportions. The clinopyroxenes of the Bag Tephra are extremely rich in Ca and Al. while the volcanic glass is rich in K indicating high-K andesitic or shoshonitic volcanism. Based on comparative geochemical analyses, the most likely origin of the Bag Tephra is the Roman or the Campanian volcanic fields in Italy. Geochemical investigation of the Paks Tephra is in progress, and preliminary results suggest the same source for this younger tephra. In contrast to the tephra horizons, the correlation of the numerous paleosols in some Hungarian loess sections and their paleoenvironmental interpretation is possible only if they are based on very detailed micromorphological studies. The age determination of the loesses containing the paleosols, directly by thermoluminescence (TL) and infrared stimulated luminescence (IRSL), and indirectly by (14)C-based isotope work, should provide a reliable basis For the identification of soil forming periods in different parts of the Carpathian Basin.

Its age is poorly defined between 788 and 380 ka B.P. The glass and mineral composition - micropumice clasts of phono-tephrite and blocky shards of tephri-phonolite associated with two kinds of clinopyroxene, fassaitic diopside, and salite - is very distinctive. This tephra could be used as a chronological marker, as soon as its age is refined. The probable origin is the middle Italian volcanic area. LA - English DB - MTMT ER -
