Obsidian Sourcing SAA
The International Association of Obsidian Studies (IAOS) is sponsoring a session at the 79th Annual Meeting of the Society for American Archaeology, in Austin, TX, .
Organizer: R. Tykot.
Working title: The Gold Anniversary of Obsidian Sourcing: 50 Years of Research Around the World.
Short description: This session honors the 50 years of research on sourcing obsidian since the 1964 publication by J.R. Cann & C. Renfrew.
Obsidian sourcing in Cappadocia
The archaeological survey conducted by the Istanbul University in the Göllüdağ volcanic complex in Cappadocia allowed us to map in detail the obsidian bearing formation of the Göllüdağ and the Nenezidağ. 246 geo-referenced obsidian samples are analyzed using LA-ICP-MS offering a new basis for sourcing. We propose a classification integrating for the first time geological, geochemical and spatial data. As a complement, 700 pieces of obsidian were used to determine the magnetic properties of the Göllüdağ’s obsidians. On these bases, new implications for obsidian sourcing will be discussed.

Obsidian Technologies in the Near-East
Obsidian studies in the Near-East rely on integrated approaches including detailed analysis of the geological complexity of volcanic massifs, the geographical distribution of sources, archaeometric signatures of the glasses and studies of the production and use of archaeological artifacts. Recent developments focused notably on the techniques employed to detach blanks and on the use and curation of tools. These methods allow us to reach different levels of interpretation. Our aim is here to illustrate with the help of several examples in which way they can throw light on the socio-economic contexts of diffusion and use of obsidian, the function of sites and the evolution of technical traditions.
