A Systematic Approach to Obsidian Source Characterization
1998A 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 loneliness of an obsidian source in southwest Manus
Archaeology in Oceania, 1997AbstractOf 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.

Sourcing archaeological obsidian by an abbreviated NAA procedure [PDF]
Journal of Radioanalytical and Nuclear Chemistry Articles, 1994 An abbreviated NAA procedure has been developed to fingerprint obsidian artifacts in the Mesoamerican region. Despite the large number of available sources, an NAA procedure, which relies on producing short-lived isotopes, has been applied with a success rate greater than 90 percent.

The Coso volcanic field reexamined: implications for obsidian sourcing and hydration dating research
, 1988Obsidian from the Coso locality, Inyo County, California, has long been regarded by archaeologists as a single “source.” However, studies by the U.S.

Ancient obsidian sources on Pantelleria (Italy)
Journal of Archaeological Science, 1988Abstract 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 ...

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.

Sources of obsidian for the Sinagua of Northern Arizona (USA)
Journal of Archaeological Science: Reports, 2018Abstract Obsidian was an important resource for prehistoric people in the North American Southwest. Elemental analysis of obsidian samples from Southwestern archaeological sites has been widely successful in identifying the raw material sources used by the people in the region.

The obsidian sources of Northland, New Zealand
Journal of the Royal Society of New Zealand, 2012Abstract 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.
