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.}, keywords = {Hungary; radiocarbon dating; mollusc; paleosol; loess; OSL and IRSL dating}, year = {2014}, eissn = {1873-457X}, pages = {140-154}, orcid-numbers = {Újvári, Gábor/0000-0002-2816-6155; Novothny, Ágnes/0000-0003-3513-0406; Páll-Gergely, Barna/0000-0002-6167-7221; Kovács, János/0000-0001-7742-5515} } @article{MTMT:2402859, title = {Status Report of the New AMS 14C Sample Preparation Lab of the Hertelendi Laboratory of Environmental Studies (Debrecen, Hungary)}, url = {https://m2.mtmt.hu/api/publication/2402859}, author = {Molnár, Mihály and Janovics, Róbert and Major, István and Orsovszki, J and Gönczi, R and Veres, Mihály and Leonard, A G and Castle, S M and Lange, T E and Wacker, L and Hajdas, I and T Jull, A J}, doi = {10.2458/azu_js_rc.55.16394}, journal-iso = {RADIOCARBON}, journal = {RADIOCARBON}, volume = {55}, unique-id = {2402859}, issn = {0033-8222}, year = {2013}, eissn = {1945-5755}, pages = {665-676}, orcid-numbers = {Major, István/0000-0003-4675-9875} } @article{MTMT:2762793, title = {Climatic fluctuations inferred for the Middle and Late Pleniglacial (MIS 2) based on high-resolution (~ca. 20 y) preliminary environmental magnetic investigation of the loess section of the Madaras brickyard (Hungary)}, url = {https://m2.mtmt.hu/api/publication/2762793}, author = {Sümegi, Pál and Gulyás, Sándor and Csökmei, Bálint and Molnár, Dávid and Ulrich, Hambach and Thomas, Stevens and Slobodan, B Markovic and Peter C, Almond}, doi = {10.1556/CEuGeol.55.2012.3.6}, journal-iso = {CENT EUR GEOL}, journal = {CENTRAL EUROPEAN GEOLOGY}, volume = {55}, unique-id = {2762793}, issn = {1788-2281}, keywords = {SUSCEPTIBILITY; Hungary; Quaternary; Atlantic Ocean; Magnetic susceptibility; paleoclimate; ice core; climate variation; paleotemperature; paleosol; marine isotope stage; loess; Atlantic Ocean (North); Greenland; Arctic; LAST GLACIAL MAXIMUM; late Quaternary; climate cycle; SE Hungary; environmental magnetism; bidecadal variations}, year = {2012}, eissn = {1789-3348}, pages = {329-345}, orcid-numbers = {Sümegi, Pál/0000-0003-1755-4440; Gulyás, Sándor/0000-0002-3384-2381; Molnár, Dávid/0000-0001-5304-0741} } @article{MTMT:1951415, title = {Atmospheric circulation patterns in central and eastern Europe during the Weichselian Pleniglacial inferred from loess grain-size records}, url = {https://m2.mtmt.hu/api/publication/1951415}, author = {Bokhorst, M P and Vandenberghe, J and Sümegi, Pál and Laczont, M and Gerasimenko, N P and Mathvisiina, Z N and Markovic, S B and Frechen, M}, doi = {10.1016/j.quaint.2010.07.018}, journal-iso = {QUATERN INT}, journal = {QUATERNARY INTERNATIONAL}, volume = {234}, unique-id = {1951415}, issn = {1040-6182}, year = {2011}, eissn = {1873-4553}, pages = {62-74}, orcid-numbers = {Sümegi, Pál/0000-0003-1755-4440} } @article{MTMT:2218443, title = {Investigating the penultimate and last glacial cycles of the Sutto loess section (Hungary) using luminescence dating, high-resolution grain size, and magnetic susceptibility data}, url = {https://m2.mtmt.hu/api/publication/2218443}, author = {Novothny, Ágnes and Frechen, M and Horváth, Erzsébet and Wacha, L and Rolf, C}, doi = {10.1016/j.quaint.2010.08.002}, journal-iso = {QUATERN INT}, journal = {QUATERNARY INTERNATIONAL}, volume = {234}, unique-id = {2218443}, issn = {1040-6182}, abstract = {The loess-paleosol record at Sutto provides an excellent high-resolution archive of climate and environmental changes. Loess deposits with a thickness of 20 m cover the travertine at Sutto in the northern part of Hungary, next to the right bank of the Danube River. The loess sequence is intercalated with two greyish stratified horizons, three brownish steppe-like soils and a pedocomplex, including a reddish-brown paleosol covered by a chernozem-like paleosol. Detailed infrared stimulated luminescence (IRSL) dating was carried out, revealing more or less continuous sedimentation from Marine Isotope Stage (MIS) 6-MIS 2. Sedimentological and paleomagnetic investigations have been performed to provide a high-resolution study of the Sutto loess paleosol sequence, in order to reconstruct the paleoclimate and environmental changes during the penultimate and last glacial cycles. Grain size and magnetic susceptibility (MS) records of the Sutto profile basically show similar patterns to those of other European loess sections. However, small differences are traced at Sutto, including more intensive deposition of coarser grained materials during MIS 6-4. The loess record at Sutto has a transitional position within the European loess belt, as its sediment was deposited under an intermediate climate between the loess successions from the southern Carpathian Basin, which accumulated under drier climate, and the loess sequences from Western Europe, which developed under wetter climate during the Middle and Late Pleniglacial.
