Geographic Coverage Obsidian sources in Oregon, California, Washington, Idaho, Nevada, Wyoming, New Mexico, Arizona, Utah, Colorado, Montana, South Dakota, British Columbia, and the Western Mediterranean are well covered; incomplete but improving coverage for Alaska, and other scattered areas in the Mediterranean, Mexico, Middle East, and Pacific islands. Fine-grained volcanic (FGV) source identification is available although is now limited primarily to artifacts from the Lake Tahoe area of east-central California.
Source List Available? Yes - all obsidian sources included in the Northwest Research reference database are listed at the lab Web site. Descriptions of many of the sources can also be found at the U. S. Obsidian Source Catalog.
Reporting Report with data tables suitable for standalone use or as an appendix (paper and Adobe Acrobat).
Payment Invoices are normally sent upon completion of project - payment may be made with cash, check, M.O., P.O., PayPal, Visa, or MasterCard.
Comments Reports can be customized upon request. We maintain a very active research program and are constantly adding new sources to our reference database. We will analyze limited quantities of geologic obsidian source material at no charge for sources that we do not currently have in our reference collection. If you would like to take us up on this offer, please contact us for details. We are also interested in geoarchaeological studies of geologic sources of obsidian and will provide analytical support for graduate students with an interest in this topic.
