Dating back to marine isotope stage (MIS) 10, the more than 10 m thick loess sequence includes four fossil soil-complexes developed in homogenous and relatively fine silty loess. Because of the good preservation of the sediment, Semlac is regarded as a key section for the Carpathian Basin, which offers possibilities to a) improve the understanding of the type and composition (loess homogeneity and pedogenic alteration) of the lowland loess sequences in the Carpathian Basin also beyond the last interglacial palaoesol complex, b) to reconstruct the temporal evolution of the local loess-palaoesol successions, c) gain better insight into the regional paleoenvironments of the last 300 ka and d) to compare the loess of the region to loess-sequences in adjacent areas and to dust proxy data in the northern hemisphere.\r\n\r\nAn integrated age model based on correlation to reference records and luminescence dating is compiled. Applying this age model we compare climate proxy data from Semlac to both global data and to data from the very southeast of the Carpathian Basin (Vojvodina, Serbia).\r\n\r\nThe obtained results provide new insight into the dust accumulation regime for the eastern Carpathian Basin and offer new palaeoenvironmental information for the region and are an important step towards establishing a catena from the thin loess-like sediments of the Banat foothills in the East towards the thicker and seemingly more complete loess sections of the south-eastern and central Carpathian Basin. Disentangling grain size data from soil formation proxies is used to investigate patterns of non-local dust. Patterns of non-pedogenetic fine material are similar to grain size proxies from China and other parts of the northern hemisphere, suggesting western and eastern Eurasian loess to have (at least partly) similar mechanistic/climatic origins.","type":"researchdata_literature","resources":[{"description":"","format":"URL","url":"http://www.sciencedirect.com/science/article/pii/S0277379116304991","created":"2017-03-08T13:04:57.534321","state":"active","package_id":"9b8d191f-21e1-4331-bc00-53607f9d45f2","last_modified":"2021-10-24T03:10:00","id":"6e3306d6-4867-46fa-9fa7-570ba08a86c6","name":"Sciencedirect"},{"description":"","format":"URL","url":"https://doi.pangaea.de/10.1594/PANGAEA.859304","created":"2017-03-08T13:04:58.059038","state":"active","package_id":"9b8d191f-21e1-4331-bc00-53607f9d45f2","last_modified":"2021-10-24T03:10:00","id":"f36cdb77-c570-4814-8c12-98879654dc64","name":"Pangaea dataset"}],"tags":[{"name":"GQT2"},{"name":"LRQ10"},{"name":"carpathian basin"},{"name":"dust"},{"name":"environmental magnetism"},{"name":"loess"},{"name":"palaeoclimate"},{"name":"palaeosols"},{"name":"quaternary"}],"extras":[{"key":"bibtex:address","value":""},{"key":"bibtex:author","value":"Zeeden, Christian and Kels, Holger and Hambach, Ulrich and Schulte, Philipp and Protze, Jens and Eckmeier, Eileen and Markovic, Slobodan and Klasen, Nicole and Lehmkuhl, Frank"},{"key":"bibtex:booktitle","value":""},{"key":"bibtex:citation","value":""},{"key":"bibtex:doi","value":"10.1016/j.quascirev.2016.11.002"},{"key":"bibtex:editor","value":""},{"key":"bibtex:howpublished","value":""},{"key":"bibtex:isbn","value":""},{"key":"bibtex:journal","value":"Quaternary Science Reviews"},{"key":"bibtex:month","value":""},{"key":"bibtex:number","value":""},{"key":"bibtex:organization","value":""},{"key":"bibtex:pages","value":"130\u2013142"},{"key":"bibtex:publisher","value":""},{"key":"bibtex:school","value":""},{"key":"bibtex:series","value":""},{"key":"bibtex:type","value":"article"},{"key":"bibtex:key","value":""},{"key":"bibtex:url","value":""},{"key":"bibtex:volume","value":"154"},{"key":"bibtex:year","value":"2016"},{"key":"Spatial","value":"{\"type\":\"Point\",\"coordinates\":[20.929,46.113]}"}],"groups":[{"image_url":"http://crc806db.uni-koeln.de/fileadmin/template/images/projects/imageB1.png","name":"b1"},{"image_url":"http://crc806db.uni-koeln.de/fileadmin/template/images/projects/imageF2.png","name":"f2"}],"author":"Janina B\u00f6sken","author_email":false}{"help":"Update a dataset (package).\n\n You must be authorized to edit the dataset and the groups that it belongs\n to.\n\n Plugins may change the parameters of this function depending on the value\n of the dataset's ``type`` attribute, see the ``IDatasetForm`` plugin\n interface.\n\n For further parameters see ``package_create()``.\n\n :param id: the name or id of the dataset to update\n :type id: string\n\n :returns: the updated dataset (if 'return_package_dict' is True in the\n context, which is the default.
