Provenance of obsidian artifacts from the Chalcolithic site of Dava Göz in NW IRAN using portable XRF

Extending the scale of obsidian studies: Towards a high‐resolution investigation of obsidian prehistoric circulation patterns in the southern Caucasus and north‐western Iran

“…In the corpus from Nakhchivan analysed so far, the obsidian from Syunik usually predominates (< 50%), followed by that from Geghasar-Gegham (< 35%) and Gügürbaba-Meydan (about 5%), with the exception of Ovçular Tepesi (Chalcolithic, Early Bronze Age), where 70% of the artefacts were made of obsidian from Geghasar-Gegham. The same sources seem to prevail in north-western Iran (e.g., Dava Göz and Kul Tepe Jolfa (Abedi et al 2018b(Abedi et al , 2018c) (see Supplementary Data 1 in the additional supporting information). A sporadic influx from sources located further west in north-eastern Anatolia (e.g., Erzurum, Pasinler, Yağlıca) and Georgia (Chikiani) is also noteworthy, but the obsidian from each of these outcrops is generally attested by < 1% of the total number of artefacts.…”

“…Beside Godedzor, some obsidian from Syunik has been identified in the Urmiah Lake area at Hajji Firuz (in restricted quantity), Pisdeli Tepe and Yanik Tepe (Renfrew et al 1966) (see also Supplementary Data 1 in the additional supporting information), Dava Göz (Late Neolithic to Chalcolithic) (Abedi et al 2018b), Kul Tepe Jolfa (Chalcolithic to Iron Age III) (Khademi Nadooshan et al 2013;Abedi et al 2018c), and on the sites of the Khoda Afarin and Jolfa plains (Neolithic to Iron Age) (Maziar 2015;Maziar and Glascock 2017). The diversity of sources attested in the archaeological assemblages of Kul Tepe Jolfa and Dava Göz, where both Caucasian and eastern Anatolian obsidian have been found, suggests that these sites played an intermediary role in the redistribution of obsidian towards the Urmiah Lake between the Chalcolithic and the Bronze Age (Khademi Nadooshan et al 2013;Abedi et al 2015).…”

Consuming local: The new obsidian source of Ideloo (Northwestern Iran) and first evidence of use by neighbouring prehistoric communities

“…Obsidian provenance studies in Northwestern Iran have indeed shown that most sites relied on the use of several sources at once—the polysource procurement strategy described by Badalyan et al (2004). In this region, a clear preference for the sources of Gügürbaba‐Meydan and Sıcaksu‐Nemrut‐Dağ in Eastern Anatolia and Gegham and Syunik in Armenia had previously been established by Abedi, Mohammadi, et al (2018), Abedi, Varoutsikos, et al (2018), Ghorabi et al (2008), Khademi Nadooshan et al (2013), Madhavi and Bovington (1972), Maziar and Glascock (2017), Renfrew et al (1966). Nevertheless, the recurrent presence of artefacts that could not be attributed to any known obsidian source has raised the possibility of potential outcrops located in Northwestern Iran.…”

“…Mesmo com a grande utilidade da análise de isótopos de estrôncio na proveniência materiais biológicos, bem como um número crescente de isoscapes regionais e globais (Kootker et al, 2016;Emery et al, 2018;Adams et al, 2019;Ladegaard-Pedersen et al, 2020;Pacheco-Forés et al, 2020;Scaffidi e Knudson, 2020;Snoeck et al, 2020;Lugli et al, 2022), os desafios permanecem no seu uso para estabelecer proveniência (Ascough et al, 2018;Holt et al, 2021). As principais questões ainda a serem enfrentadas nos trabalhos com os isótopos de estrôncio e seu uso para atribuição de origem são as seguintes:…”
