High-resolution proxy record of the environmental response to climatic variations during transition MIS3/MIS2 and MIS2 in Central Europe: The loess-paleosol sequence of Katymár brickyard (Hungary)

Paleoclimate reconstruction and mire development in the Eastern Great Hungarian Plain for the last 20,000 years

“…Increasing Typha sp. pollen percentages were already detected from 25,000 cal yr BP at Lake Fehér (Sümegi et al, 2018), and seeds were discovered from 17,470 cal yr BP in Lake Balaton (Jakab et al, 2005).These findings together with the results of climate model simulations (15-17°C by Renssen et al (2001)) support our relatively warm July mean temperature inferences and also warn us that the minimum thermal tolerance requirements of aquatic taxa were already exceeded in the lowland areas during the early LPG period. (Gaillard, 2007;Hannon and Gaillard, 1997a), while Hippuris was also part of the first pioneer plant communities in Switzerland, although became dominant rather later, around 15,100 cal yr BP when July temperatures increased to more than 13°C (Gaillard, 2007;Hannon and Gaillard, 1997a).…”

Selected Grain-Size and Geochemical Analyses of the Loess-Paleosol Sequence of Pécel (Northern Hungary): An Attempt to Determine Sediment Accumulation Conditions and the Source Area Location

“…The grain size composition was carried out with an Easysizer 20 laser sedigraph at the Department of Geology and Paleontology, University of Szeged. The source used is a 2 MW of energy, 0.6328 µm wavelength He-Ne laser [14]. The laser sedigraph measured 42 particle size ranges between 0.0001 and 0.5 mm using 54 built-in detectors based on the Mie scattering theory.…”

“…The complex investigation of loess-paleosol profiles aims at the detection of paleoclimatic and paleoecological changes of the Quaternary period [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. The sedimentological (particle size composition) and geochemical analyses of loess-paleosol sequences can reveal environmental factors like the prevailing wind direction [17][18][19], wind intensity [20], precipitation intake [21] and weathering conditions and parameters [22,23].…”

“…The highresolution sampling of the profiles supported by a sufficient amount of age data allows the examination with the resolution of decades and centuries. Our sediment samples cover a relatively short time interval because of the resolution of the sampling (4 cm), which provides the detection of so-called microcycles [14,15,24].…”

“…Quaternary studies in Hungary can be supplemented with additional information with the 20-30-m-high profile of Pécel. It has a unique location in contrast to the loess-paleosol profiles of lowland (e.g., [12,14,15,[27][28][29]) and foothill (e.g., [11,19,30,31]) regions of Hungary. Because of it, the North Hungarian Mountains and Buda Hills could play a role in the origin of the sediment of the Pécel profile.…”
