The Paredón, Mexico, Obsidian Source and Early Formative Exchange

Science, 1978
In 1975, archeological surface surveys of trade routes located again a pre-Hispanic obsidian source in central Mexico first reported in 1902. Initial trace element studies of the Paredón source through an analysis by neutron activation have been compared with similar studies of the obsidian found at Chalcatzingo 150 kilometers from the source.

A Systematic Approach to Obsidian Source Characterization

1998
A systematic approach to sample collection, chemical analysis, and statistical evaluation of obsidian sources is recommended before significant numbers of artifacts should be analyzed. Multivariate statistical methods based on Mahalanobis D 2 enable robust rejection of erroneous source assignments and lead to sourcing of artifacts with a very high ...

The obsidian sources of Northland, New Zealand

Journal of the Royal Society of New Zealand, 2012
Abstract Four sources of obsidian have previously been recognized in Northland, but more recent field observations and new chemical analyses indicate there are three (Pungaere, Otoroa and Huruiki). Obsidian from these sources can be readily distinguished on the basis of visual characteristics and chemical attributes.

Obsidian in Southern Ecuador: The Carboncillo Source

Latin American Antiquity, 2011
AbstractThe Carboncillo area in the southern highlands of Ecuador is identified as the only confirmed source of archaeological obsidian located in the country outside of the northern highlands and is the first identified in the large gap between the known Ecuadorian and Peruvian sources.

Ancient obsidian sources on Pantelleria (Italy)

Journal of Archaeological Science, 1988
Abstract Neolithic and Late Bronze Age obsidian tools with a sodic peralkaline composition but which are measurably different from those of this chemical type studied previously have been found for the first time in Sicily. Since all these peralkaline obsidians are believed to originate on Pantelleria, this finding poses the problem of the number of ...

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.
