No full textInstrumental neutron activation analysis was applied to determination of some major, minor and trace elements in pigments and binding medium, collected from the fresco “Sant’Agata al Monte” kept at the Civici Musei, Pavia. Chemical composition indicates that the nature of pigments was mainly mineral. Trace element content of binding media, when compared with similar samples from well known and dated paintings, may be useful in the identification of fake artifacts

No full textProvenance studies of obsidian artefacts from turkish neolithic sites. An interdisciplinary approach by INAA and fission track dating.
No full textThis work reports the results of an interdisciplinary study aimed to contribute to a better understanding of circulation of obsidian during prehistoric times in Turkey. Fission-track (FT) dating and trace element composition by instrumental neutron activation analysis (INAA), were applied to obsidian artefacts from four Neolithic sites of eastern Anatolia and from Hocaçeçme, which is located near the Greek border, in the Edirne region. Both INAA as well as FT dating confirm that a variety of sources can be represented in the same site in the same stratigraphie level. Whereas the Anatolian studied sites yielded only artefacts originated from eastern Anatolian sources, those of Hocaçeçme have a Anatolian provenance (Gôllûdag and Hasandag volcanic complexes). An unambiguous identification was attained for some eastern Anatolian sources - the Bingôl and the Nemrut Dagi obsidians. For other sources only a generic attribution to the Bingôl - Mu§ - Karliova triangle and to the Quaternary volcanic edifices located along the north coast of Lake Van can be made. Results of this study confirm that further detailed field work is needed in order to attain an adequate stage of knowledge of the Anatolian potential natural sources of raw material of prehistoric obsidian artefacts.Ce travail présente les résultats d'une étude interdisciplinaire destinée à mieux comprendre la circulation de l'obsidienne durant la préhistoire en Turquie. La datation par traces de fission de l'Uranium (T.F.) et l'analyse élémentaire (INAA) ont été appliquées aux obsidiennes de quatre gisements néolithiques d'Anatolie orientale ainsi qu'à celui de Hocaçeçme dans la région d'Edirne, près de la frontière grecque. INAA comme T.F. indiquent la présence de plusieurs sources représentées dans un même gisement pour un niveau donné. Alors que les sites étudiés d'Anatolie ne contiennent que de l'obsidienne provenant d'Anatolie orientale, celui de Hocaçe§me a livré de l'obsidienne provenant d'Anatolie centrale (complexes volcaniques de Gôllûdag et de Hasandag). Certaines sources d'Anatolie orientale ont été clairement identifiées : Bingôl et Nemrut Dagi. Pour les autres sources, seule une attribution générique au triangle Bingôl-Mu§- Karliova d'une part et aux édifices quaternaires situés sur la côte nord du lac Van, d'autre part, ont pu être proposées. Ces résultats confirment que des études de terrain détaillées sont encore nécessaires pour obtenir une bonne connaissance des sources potentielles d'approvisionnement en matière première pour l'industrie lithique préhistorique.Oddone Massimo, Yeğingil Zehra, Özdoğan Mehmet, Meloni Sandro, Bigazzi Giulio.
