A New Obsidian Source in the Highlands of Guatemala

Ancient Mesoamerica, 1992
AbstractA new obsidian source has recently been discovered in the highlands of Guatemala, near the city of Sansare, El Progreso. Ten samples have been subjected to neutron activation analysis, and the results are presented. While ceramic affinities tie the Sansare area with Formative and Classic period Highland Maya sites, linguistic evidence suggests ...

The prehistoric sources of Palliser Bay obsidian

Journal of Archaeological Science, 1978
Abstract A sample of 210 pieces of archaeologically derived obsidian from settlement sites in Palliser Bay, New Zealand, was subjected to X-ray fluorescent analysis, in order to define the petrographic sources exploited by these prehistoric groups. It was found that the material had been derived from sources at Mayor Island, Huruiki, Rotorua, Cooks ...

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 ...

Western Oneota Obsidian: Sources and Implications

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

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.

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.

The loneliness of an obsidian source in southwest Manus

Archaeology in Oceania, 1997
AbstractOf two obsidian source areas in the Admiralty Islands (Manus Province, Papua New Guinea), only the Lou‐Pam Islands source has a well‐established place in archaeological distributions both local and regional. From the other source area in southwest Manus Island, many sites have been recorded following their exposure by bulldozers.

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 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.
