Central to this model is the Carpathian Basin, a region covering most of the Middle Danube. As the archaeological record of this region is still poorly understood, this paper aims to provide a contextual assessment of the Carpathian Basin’s geological and paleoenvironmental archives, starting with the late Upper Pleistocene. Subsequently, it compiles early Upper Paleolithic data from the region to provide a synchronic appraisal of the Aurigna- cian archaeological evidence. It then uses this data to test whether the relative absence of early Upper Paleolithic sites is obscured by a taphonomic bias. Finally, it reviews current knowledge of the Carpathian Basin’s archaeological record and concludes that, while it cannot reject the Danube corridor hypothesis, further (geo) archaeological work is required to understand the link between the Carpathian Basin and Central and Southeastern Europe. 2018-06-11T06:24:36+02:00 On the role of spatially inhomogeneous diabatic effects upon the evolution of Mars’ annular polar vortex The structure of Mars’ annular polar vortex is not similar to that of its counterpart on Earth and is characterised by a potential vorticity (PV) low in the vicinity of the winter pole, rather than PV monotonically increasing towards the pole. A number of persistent asymmetric high-PV patches around the central low are also typical for the Martian polar vortex. The simplest vertically averaged model of the Mars atmosphere (a rotating shallow water model on the polar tangent plane) with inclusion of diabatic effects is used to get clues for understanding this surprising behaviour. The standard parameterisation of radiative relaxation is applied, together with a simple parameterisation of latent heat release due to spatially inhomogeneous CO2 deposition. The parametrisation of inhomogeneous deposition is new in this type of models, and includes dependence on the concentration of condensation nuclei, which are considered as a passive tracer. Linear stability analysis of the zonally and time averaged Mars’ winter polar vortex is performed, and thus identified unstable modes are used for initialisation of high-resolution numerical simulations of their nonlinear evolution in four different configurations (adiabatic, diabatic with only radiative relaxation, only deposition, and both radiative relaxation and deposition), in order to identify the role of each process. It is shown that the combined effect of radiative relaxation and inhomogeneous deposition can account for the observed, formally unstable structure of the polar vortex, including the patches of high potential vorticity. 2018-06-06T20:42:12+02:00 Geological formations and deposits containing lithic raw material in Rhineland and neighbouring regions The GIS dataset contains 19 recent geological formation/ deposit shapefiles that keep lithic raw material used during the Mesolithic also as the Paleolithic and Neolithic period. The geological data was gained from published digital maps (Carte géologique du Grand-Duché de Luxembourg 1998, GÜK200 2007, NRW: IS GK 100 DS 2009, Surface lithology (INSPIRE) 2016) whereas archaeological site inventory and lithic raw material distribution data was gained during the D4 project phase (CRC 806). Further, out of the D4 project database 6 additive datasets where created describing the location of a singular Meuse gravel flint deposit in Hambach, former tertiary quartzite and chalcedony sources (Floss 1994), outcrop locations from raw material surveys (e.g. Gehlen et al. 2015) also as extraction sites. The spatial analysis of lithic raw material sources is a valuable tool to identify and quantify Mesolithic foraging areas through different stages (e.g. Early Mesolithic). Based on the combination of geological data and the D4 sites database potential Mesolithic foraging areas could have been calculated for the D4 study area located in Germany (NRW, Hessen, Rhineland-Palatinate, Saarland), Luxembourg, Belgium (Wallonia) and the southern Netherlands (Limburg). 2018-05-31T12:35:35+02:00 Mikromorphologische Untersuchung des spätpaläolithischen Fundplatzes Blazi Cave (Albanien) -Die Blazi Cave im nordalbanischen Karst liegt auf einer Höhe von 276 m (ü. NN) und ist ca. 50 km von der Adriaküste entfernt. Das Portal ist nach Südwesten orientiert. -Sie ist durch die Arbeiten von Prendi & Andrea (1981) bekannt für ihren bronzezeitlichen und neolithischen Fundreichtum. Paläolithische Funde wurden damals als ‘preneolithisch’ angesprochen. -Während der Grabung des German-Albanian Paleolithic survey (GAP) 2015 wurden zahlreiche lithische Artefakte aus dem Epigravettien (Spätpaläolithikum) gefunden. Blazi Cave ist seitdem der erste durch Typologie und Radiokarbondatierungen bestätigte Epigravettienfundplatz in Albanien (Hauck et al. 2016). -Ziel der Arbeit war es, die fundplatzbildenden Prozesse in Grabungschnitt V mikromorphologisch zu untersuchen. -Für die Interpretation des Fundkontextes wurde zudem pro Profilschicht und Mikrofazies eine graphisch-statistische Auswertung der Porosität sowie der Verteilung von Holzkohle, Knochen- und lithischen Artefaktfragmenten erstellt. -Die vielen Holzkohlefragmente und die gute Sichtbarkeit der Zellstruktur in den Dünnschliffen bot die Möglichkeit, die zugehörige Pflanzengattung zu bestimmen. -Die Verteilung der lithischen Artefaktfragmente mit ihrer unterschiedlichen Petrographie legt die Differenzierung zweier Nutzungsphasen im Epigravettien nahe. -In der unteren Fundschicht konnten Anzeichen für das Vorhandensein eines Laufhorizonts festgestellt werden. -Die mikromorphologische Analyse ergab zudem Hinweise auf sehr wechselhafte Klimabedingungen seit dem letzten glazialen Maximum (LGM). 2018-05-31T11:47:59+02:00 Luminescence dating of eolian and fluvial archives in the Middle and Lower Danube catchment and the paleoenvironmental implications 2018-05-24T07:04:18+02:00
