The project members have acquired data from different geographical areas. In Central Anatolia, we contributed to a survey led by Nur Balkan-Atlı of the obsidian sources of the Göllüdağ and Nenezidağ (Department of Prehistory, Istanbul University) which began in 2007. The main goals were the detailed mapping of the obsidians, the development of a GIS for the Göllü Dağ region articulating both chemical and magnetic analyses of geological obsidians and archaeological data (collaboration CNRS/IFEA-ITÜ/EIES with the Istanbul University team of N.Balkan-Atlı, Arizona University, IRAMAT/Orléans, LSCE/Gif-sur-Yvette), together with technological analysis of the archaeological material. The technological and/or the techno-functional analyses of archaeological assemblages in the Konya Plain and in Cappadocia have been conducted in collaboration with Istanbul and Liverpool Universities. Pınarbaşı, Boncuklu and the earliest levels of Aşıklı Höyük offer opportunities to re-evaluate the spread of farming and the early development of sedentism in Central Anatolia from 12000 and 8300 cal. BC. The inter-relashionship between the adoption of the Neolithic way of life and the florescence of elaborate symbolic expression and specialized craftsmanship is also being studied. We have focused on the technological and tribological analysis of prestige objects found in Aşıklı höyük (ca 7500 cal. BC), Domuztepe and Arpachiyah (Halaf) in collaboration with the Universities of Istanbul and Manchester, the LTDS of the Ecole Centrale de Lyon and the CNRS/IFEA. In addition we have documented the presenece of large blades produced with the help of a lever by pressure. These obsidian blades are now well known in Cayönü Tepesi (in collaboration with Istanbul University, the Mission de Préhistoire Anatolienne and a contribution from OUP team-CNRS/IFEA) and Sabi Abyad (collaboration Leiden University and CNRS/ArScan/IFEA). Within this project, a technological analysis of the stone tools from Gelveri is underway. The studies conducted on the sites shown on the map below have already produced important results awaiting publication.
