Origins of obsidian at the “Pompeii of the Syrian Desert:” Sourcing lithic artifacts from the Yale-French excavations at Dura-Europos

Journal of Archaeological Science: Reports, 2019
The Hellenistic, Parthian, and Roman site of Dura–Europos (or simply “Dura”), dubbed the “Pompeii of the Syrian Desert” by Yale historian and archaeologist Michael Rostovtzeff, was jointly excavated by Yale University and the French Academy of ...

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.

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 classification and defining “local” in early Holocene Southeast Alaska

Geoarchaeology, 2022
Despite the ubiquity of obsidian in early Holocene archaeological assemblages across Southeast Alaska, artifact sourcing using bi‐plots and Principal Component Analysis has been hampered by the highly correlated geochemistry of two major sources: local ...

Identifying the Geographical Source of Artefact Obsidian

Nature, 1966
DURING an avocational search for means of identifying the geographical source of artefact obsidian, what appears to be a functional tool has been found. It was postulated that, because the concentration ratio in rocks is determined by the origin and age of the rock, it would also ...

Obsidian Sources Characterized by Neutron-Activation Analysis

Science, 1968
Concentrations of elements such as manganese, scandium, lanthanum, rubidium, samarium, barium, and zirconium in obsidian samples from different flows show ranges of 1000 percent or more, whereas the variation in element content in obsidian samples from a single flow appears to be less than 40 percent.

Obsidian Sources in Guatemala: A Regional Approach

American Antiquity, 1978
Geologic sources of obsidian are frequently treated in the archaeological literature as single, discrete flows, each being recognized as a different source as long as it can be geographically isolated. However, some recent studies show a tendency toward the correction of this misconception, and toward defining operationally the obsidian source concept ...

The Italian obsidian sources

2005
In Europe obsidian is a very rare material, in comparison with other sectors of Earth, such as, for example, the adjacent Near East. In Western Europe obsidian workable by prehistoric men was recognised only in four volcanic complexes, located in the IIalian islands of Sardinia, Palmarola, Lipari and Pantelleria.
