It is embedded in the multi-disciplinary CRC\r\n806 \u201cOur Way to Europe,\u201d also investigating other regions including the source areas\r\nin North-East Africa, the North-African/Southern-European-Corridor, the Balkans and\r\nCentral Europe.\r\nThe timeframe of the Marine Isotope Stage (MIS) 4\u20132 (74\u201312 ka) is very important for\r\ngeoarchaeological research, especially in Jordan, where sites and palaeoclimatic evidence\r\nare still lacking. We focus on the reconstruction of the Upper Pleistocene landscape\r\nevolution around archaeological sites in the presently arid environment of theWadi Sabra\r\n(South-Central Jordan). The study is based on sedimentological and geochemical analysis\r\nof terrestrial sedimentary deposits. The study area is situated in the Greater Petra area\r\nin the eastern escarpment of the Dead Sea Rift. In this region, the Wadi Sabra valley\r\nsystem developed along a NE-SW striking tectonic fault line and recently drains the\r\nJordanian plateau towards the west (Fig. 1). In altitudes from 600 to 800m a.s.l., up to\r\n30m of stratified wadi deposits have been preserved from modern erosion. Determined\r\nby the nature of the local bedrock (Palaeozoic sandstones), the wadi fills are mostly\r\nof sandy composition. The association with archaeological finds of the Middle to the\r\nFinal Palaeolithic (\u001850\u201318 ka) allows a reconstruction of palaeoenvironmental conditions\r\nduring and after the time of the initial human occupation. Here we intend to present\r\na preliminary model of landscape development in the Wadi Sabra based on field work\r\nimpressions and laboratory data analyzed to date.","type":"researchdata","resources":[{"description":"","format":"URL","url":"http://journal.topoi.org/index.php/etopoi/article/view/126","created":"2015-01-29T18:26:41.710003","state":"active","package_id":"fe700de7-2d15-4d62-9b23-4d0e77f9f1d1","last_modified":"2021-10-22T15:10:57","id":"981bc19d-382e-4a86-82a1-90f2b4aee7c1","name":"http://journal.topoi.org/index.php/etopoi/article/view/126"}],"tags":[],"extras":[{"key":"bibtex:address","value":""},{"key":"bibtex:author","value":""},{"key":"bibtex:booktitle","value":""},{"key":"bibtex:citation","value":""},{"key":"bibtex:doi","value":""},{"key":"bibtex:editor","value":""},{"key":"bibtex:howpublished","value":""},{"key":"bibtex:isbn","value":""},{"key":"bibtex:journal","value":""},{"key":"bibtex:month","value":""},{"key":"bibtex:number","value":""},{"key":"bibtex:organization","value":""},{"key":"bibtex:pages","value":""},{"key":"bibtex:publisher","value":""},{"key":"bibtex:school","value":""},{"key":"bibtex:series","value":""},{"key":"bibtex:type","value":""},{"key":"bibtex:key","value":""},{"key":"bibtex:url","value":""},{"key":"bibtex:volume","value":""},{"key":"bibtex:year","value":"2012"},{"key":"Spatial","value":"{\"type\":\"Point\",\"coordinates\":[35.42,30.29]}"}],"groups":[{"image_url":"http://crc806db.uni-koeln.de/fileadmin/template/images/projects/imageB1.png","name":"b1"}],"author":"Dr. Rene L\u00f6hrer","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.
