These materials were supposed to be mixed during transport before being captured in karstified fissures. Evidence that the eolian fissure sediments of Plio-Pleistocene age in the older Triassic-Cretaceous limestones are derived from eolian silt and clay includes compositional and textural matches, especially decreasing grain-size trends observed downwards from the paleo-surface of the former landscape. Various environmental factors could be recognized by the statistical evaluation of grain-size distribution curves of fissure fillings sediments, such as the effects of eolian transport, parent rock type, weathering, and other sediment transport processes. Grain-size distribution curves with a single maximum in the silt size range are typical for the overlying siltstone debris, for the redeposited loess and red paleosol underlying the loess. Red clay fissure fillings yield bimodal grain-size distribution curves with maxima both in the clay and silt fractions. The research reported in this paper identifies for the first time the presence of eolian deposits in karst fissures of the Carpathian Basin and investigates the characteristics and origin.}, year = {2020}, eissn = {2296-6463}, orcid-numbers = {Kovács, János/0000-0001-7742-5515; Újvári, Gábor/0000-0002-2816-6155; Varga, György/0000-0003-4784-6372; Szabó, Péter/0000-0003-0827-3583} } @CONFERENCE{MTMT:31277862, title = {Saharan dust events in the Carpathian Basin (Central Europe) in 2018: provenance analyses by granulometry, XRD and SEM methods}, url = {https://m2.mtmt.hu/api/publication/31277862}, author = {Kovács, János and Gammoudi, Nadia and Kovács, A and Varga, György}, booktitle = {EGU General Assembly 2020: Abstracts}, doi = {10.5194/egusphere-egu2020-10111}, unique-id = {31277862}, year = {2020}, orcid-numbers = {Kovács, János/0000-0001-7742-5515; Varga, György/0000-0003-4784-6372} } @CONFERENCE{MTMT:31277855, title = {40-years of Saharan dust events in the Carpathian Basin: background, frequency, intensity, changing patterns}, url = {https://m2.mtmt.hu/api/publication/31277855}, author = {Varga, György and Gammoudi, Nadia and Kovács, János}, booktitle = {EGU General Assembly 2020: Abstracts}, doi = {10.5194/egusphere-egu2020-20517}, unique-id = {31277855}, year = {2020}, orcid-numbers = {Varga, György/0000-0003-4784-6372; Kovács, János/0000-0001-7742-5515} } @article{MTMT:30617512, title = {Changing temporal patterns and intensity of Saharan dust events in (Central) Europe}, url = {https://m2.mtmt.hu/api/publication/30617512}, author = {Varga, György and Gammoudi, Nadia}, journal-iso = {GEOPHYS RES ABSTR}, journal = {GEOPHYSICAL RESEARCH ABSTRACTS}, volume = {21}, unique-id = {30617512}, issn = {1029-7006}, year = {2019}, eissn = {1607-7962}, orcid-numbers = {Varga, György/0000-0003-4784-6372} }
