IRTG Colloquium June 15th @ 3 PM – PhD talk by Cristina Val Peon

Palaeoenvironmental evolution in SW Iberia during the Late Pleistocene and the Holocene

Considering southern Iberia as a key territory in terms of geoarchaeology and biodiversity, this project aims to enrich the knowledge on how palynological records mirror some abrupt events, discern the possible causes to some long term trends in vegetation, and understand the impact of palaeoenvironmental changes in human populations from the LGM to the Late Holocene.

Taylor Otto: Faunal Resource Selection in the Late Glacial of the Western Mediterranean

by Taylor Otto,
University of Cologne

In this talk I will present the results of the site research for my PhD. Analyzing the faunal data from Late Glacial sites in the Western Mediterranean, some temporal and spatial trends could be identified. 

It seems that Greenland Interstadial 1 (15-13ka) brought along changes in the large mammal spectrum, in addition to the addition of snails to the diet, that cannot be identified for the Iberian Peninsula.

Marine Simon: Comparisons as a Method in Geography Textbooks: Results from an International Comparative Analysis

by Marine Simon,
University of Cologne

Although comparing tasks are widely used in geography classes, there is neither a framework for their implementation nor a scientific study of their precise use. This presentation aims to present the theoretical framework, the methods and the first results of an international study of 20 textbooks form Germany, France and England. 

In this study, we develop a reliable typology and a framework for the categorisation of comparison tasks’ objectives that can contribute to transform comparison tasks into meaningful tasks aiming at enhancing pupils’ autonomous and critical thinking as well as geographical skills and methods.

Jonathan Schoenenberg: Geopal – Reconstructing Upper Palaeolithic Land Use Pattern

by Jonathan Schoenenberg,
University of Cologne

Based on the methodology of landform-based biodiversity modelling, which was developed in the project “GIS-based reconstructions of Late Palaeolithic land use patterns of the Northeast-Bavarian low mountain range”, this research aims to the analysis of organic resource potential in the territories of Upper Palaeolithic sites on a European scale. By the synchronous and diachronic comparison of the economic conditions and the landscape-accessibility throughout the Upper Palaeolithic, regional patterns can be identified and insights into the respective land use pattern can be gained. An important role plays the accessibility of the site’s periphery. It is strongly determined by the local topography and ground cover and profoundly influences the economic opportunities that can be exploited by hunter-gatherer groups. A Further aspect of the research is the comparison of European time slices and cultures with the Early Ahmarian in the Levant, to track anatomically modern humans on their way to Europe.

Timon Netzel: Quantitative climate reconstructions

by Timon Netzel,
University of Cologne

In this talk two quantitative climate reconstructions are presented. One of the reconstructions contains several timeslices (17,000 BP – present) and one gridpoint in space (Lake Prespa). The other reconstruction contains one timeslice (mid-Holocene) and several gridpoints in space (Europe). Both reconstructions are based on several proxies (pollen, macrofossils and speleothems) and new transfer functions.

Sebastian Szyja: Mind the Gap – The Westphalian Basin within the context of the resettlement of Europe after the LGM

by Sebastian Szyja,
University of Cologne

The Westphalian Basin lacks evidence of human presence during the Late Upper Palaeolithic (c. 18-14 ka cal BP), which stands in clear contrast to its neighboring regions. To the North, the Hamburgian is present from c. 15 ka cal BP, while the Magdalenian is well known from the Rhine-Meuse and the Elbe-Saale area from around 16 ka cal BP. 

The existence of this “No Man’s Land” between the Magdalenian and Hamburgian settlement zones has been argued before but the different factors, which might have led to this situation have never been critically evaluated. Using data from the two bordering Magdalenian settlement zones (Rhine-Meuse & Elbe-Saale), GIS-based predictive archaeological modeling will be applied to investigate the potential for a Magdalenian occupation in Westphalia according to the topographic and economic conditions. It will then be possible to compare the suitability of the region with the inhabited areas and to answer the question if Magdalenian hunter-gatherers avoided the Westphalian Basin because it was less attractive for them then the surrounding regions.  

Other factors may also be responsible for the fact that no sites from this time period could be found in Westphalia. Therefore, the occurrence of postsedimentary processes like modern land use, sedimentation/erosion and activity of avocational collectors in each region will be evaluated and compared with the predictive archaeological model. These source-filters may dramatically influence site-visibility and skew the archaeological record in the region. By comparison of both settlement pattern analysis and source-filtering we hope to be able to provide better models for explaining the archaeological record visible today.

Iberomaurusian reduction sequences in northeast Morocco

poti_blog_post

North-western Africa experienced significant environmental shifts during Marine Isotope Stage 2, including periods of major aridity and intense cooling (Heinrich events 2 and 1).

In order to understand the relationship between those environmental fluctuations and the technical systems/land-use dynamics of local Late Pleistocene hunter-gatherers, the results of work recently undertaken at the archaeological site of Ifri El Baroud (NE Morocco) are presented.

Alessandro Potì, PhD Candidate in Project C2.

The site yields a well-stratified sequence of ca. 3 m thickness of LSA deposits (Early and Late Iberomaurusian) very rich in charcoal and archaeological finds. Technological analysis of the lithic assemblages compared with the study of the vertebrate fauna, molluscs and botanical remains reveal a high dynamic interplay between environmental and behavioural changes.

Ifri El Baroud is one of the few sites of the Maghreb with both Early and Late Iberomaurusian layers. For this reason it plays a relevant role in assessing the nature of continuities/discontinuities in human and landscape ecology within the context of the LSA occupation of NW Africa.

Multi-scale dimensions of relief in Geoarchaeology: A base for reconstructing Late Pleistocene environments in the Eastern Desert of Egypt

Banner_Henselowsky

Scale, spatial and temporal, is one of the most important issues to deal with, when reconstructing former environments and landscapes. Interdisciplinary research such as geoarchaeology is dealing with different disciplines, descriptions and interpretations and therefore often work with varying meanings of specific scales. As geomorphology plays a substantial part of Geoarchaeology (e.g. Fuchs & Zöller 2006, Working Group on Geoarchaeology (WGG) as subproject of the International Associations of Geomorphology (IAG)), concepts of scale from geomorphological perspective are highly recommended when discussing issues of scale in geoarchaeology. Rather than sedimentology, mineralogy or other geosciences dealing with geoarchaeological research questions, geomorphology has a broader understanding in matters of geographical space.

Felix Henselowsky, PhD Candidate in Project A1.

Based on the classification between the dimension of a landform and their persistence  (after Dikau 1988, Ahnert 1996, Bubenzer 2009), we identify three different levels of observations concerning the identification of landforms: The Microrelief (object dimension between 10-3– 10-1km), Mesorelief (10-1 – 101km) and Macrorelief (101– 103km). Each scale has significant relief forms, e.g. starting from single wadi terraces, specific catchments, and drainage network up to full mountain ranges, all of them with informative values for a specific spatial and temporal scale. In the end, a clear identification of specific scales by integrating also archaeological evidences is given to answer key research questions about landscape evolution, connectivity of regions and corridors for human migration. The talk discusses problems and challenges of this approach for the Eastern Desert as an example of a today´s hyper arid environment.

Investigating sediment thicknesses with geophysics in the East-African Rift Valley

banner_seidel
When aiming at the reconstructing of the paleoclimate, applied geophysical techniques can assist with the identification and definition of possible paleoenvironmental archives such as sedimental deposits.

three sedimentary basins within the East ­African Rift Valley using 2D transient electromagnetics (TEM) and electrical resistivity tomography (ERT). Lake Chew Bahir (“Salty lake” in Amharic, approx. 500 m a.s.l.) is a 30 km x 70 km saline mudflat that episodically fills with water during rainy season. According to airborne gravity and seismic reflection data, the thickness of its sedimentary deposits is assumed to be of several kilometers. Therefore, the basin potentially provides sedimentary archives that extend far beyond the Quaternary. The source area of Bisare River is located within the Hobitcha Caldera near Wolaita Sodo in southern Ethiopia. Former sedimentological results indicate a continuous sedimentation process and Tephra layers. The double crater system of the Dendi Lakes is located at Mount Dendi (3,270 m asl) 80 km west of Addis Ababa. First drillings revealed holocene deposits within the lake sediments. Our results indicate sediment thicknesses comprising quaternary sediments.

The recorded data was processed using the software AarhusInv from the Hydrogeophysics Group of the University of Aarhus, Denmark. Here, all data and models are inverted as one system, producing layered solutions with laterally smooth transitions. The models are regularized through lateral constraints that tie interface depths or thicknesses and resistivities of adjacent layers. These inversion schemes are well suited for data taken in sedimentary environments.
