Pacific obsidian sourcing by portable XRF

Archaeology in Oceania, 2010
AbstractThe use of portable XRF analysis to characterise the geochemistry of Pacific obsidians is reported. Obsidian source samples from New Britain, the Admiralties, Fergusson Island and the Banks Islands were successfully characterised and then used to source 966 samples of obsidian from three (SE=SZ‐8, SE‐RF‐2, SE‐RF‐6) Reef/Santa Cruz Lapita sites.

Splitting obsidian: Assessing a multiproxy approach for sourcing obsidian artifacts in British Columbia

Journal of Archaeological Science: Reports, 2019
Abstract Archaeology and geology inherently intersect when attempting to determine the geographic origin of lithic materials manufactured into artifacts by ancient people. Obsidian, or volcanic glass, is frequently found in archaeological sites, and researchers commonly use the trace element characteristics of obsidian artifacts to identify their ...

Obsidian Sourcing by X-Ray Fluorescence Analysis

Obsidian sourcing is the process by which obsidian artifacts are matched to the geological sources (e.g., a specific volcano or lava flow) from which the obsidian originated on the basis of elemental composition, sometimes termed trace-element fingerprinting.

Microblade technology, obsidian sourcing, and the Cody complex in early Holocene Alberta

Plains Anthropologist, 2020
Despite being an ephemeral presence in Plains archaeological assemblages, the distribution and technical specificity of early Holocene (Denali complex) microblade technology makes it readily identifiable and comparable to similarly-aged Paleoindian ...

Obsidian provenance studies in Colombia and Ecuador: obsidian sources revisited

Journal of Archaeological Science, 2008
The field occurrences, elemental compositions and formation ages of Colombian and Ecuadorian obsidians are revisited. It is shown that the regional sources of this raw material are linked to two major volcanic structures: the Chacana and the Paletara calderas, localised on the eastern cordillera of Ecuador and on the central Andean cordillera of south ...

Obsidian source identification at Gre Fılla, Turkey

Journal of Archaeological Science: Reports, 2021
Abstract This study presents a provenance analysis of the obsidian assemblage from Pre-Pottery Neolithic B (PPNB) at Gre Filla, in Turkey. A hand-held, portable X-ray fluorescence (pXRF) spectrometer was used to obtain the element contents of the artefacts. The major sources at the settlement were identified as Bingol B, Bingol A, and Nemrut Dag. The

New Britain obsidian sources

Archaeology in Oceania, 1997
AbstractThe natural occurrence of obsidian in volcanic flows in West New Britain has been thoroughly investigated and new measurements of the composition of field samples have been made with a proton dose of 150 μC, increased by a factor of three compared to analyses reported in early studies.

Western Oneota Obsidian: Sources and Implications [PDF]

Plains Anthropologist, 2001
Exotic lithic raw materials provide insight into exchange relations and mobility of prehistoric populations. Toward this end, obsidian flakes from two western Oneota sites, Warne in north central Kansas and Blood Run in northwestern Iowa, were sourced using x-ray fluorescence spectrometry. With the exception of two artifacts from Warne, all were traced

Tikal Obsidian: Sources and Typology

American Antiquity, 1984
The obsidian industry of Classic period Tikal, Guatemala, is discussed with regard to geological source determinations and behavioral typology. The potential of these two approaches for cultural reconstruction is greatly extended when they can supplement each other. Recent source determinations of obsidian artifacts from Tikal indicate (1) a behavioral

Source obsidian rare earth patterns and obsidian artefact provenience

Revue d'Archéométrie, 1981
The rare earth distributions in obsidian source material examined. For seven sources from Turkey examined by instrumental neutron activation analysis (INAA) the rare earth patterns provide a unique signature for the assignment of provenience for archaeological finds.
