INTERNATIONAL ASSOCIATION FOR OBSIDIAN STUDIES (IAOS)

Welcome to the International Association for Obsidian Studies (IAOS) home page. From here, you can find out about the IAOS and explore technical information related to obsidian characterization ("sourcing") studies and obsidian hydration dating methods.

IAOS BULLETIN 63 (A special issue by Sandy Rogers and Chris Stevenson) IS OUT: All issues of the IAOS Bulletin are available for downloading as searchable Adobe Acrobat documents and single back issues can be downloaded using the drop-down menu below. And don't forget that a cumulative and searchable PDF of all IAOS Bulletin issues is also available in the Member's Lounge.

SAA CANCELS 85th ANNUAL MEETING: The Society for American Archaeology 2020 Annual Meeting in Austin, Texas, has been cancelled. The IAOS Annual Meeting, held during the SAA Annual Meeting, has been put on hold and we're currently working on an alternative. I'll post updates here as they're available.

THE IAOS PDF LIBRARY: We're assembling a slowly-expanding collection of obsidian-related theses and dissertations, all in searchable Adobe Acrobat (PDF) format. If you have a thesis or dissertation that you'd like to contribute to the newly-refocused PDF library, we would very much like to hear from you! To add a reference to the library, simply send an email to obsidianlab@gmail.com, write "IAOS LIBRARY" in the subject line of the email, and attach the PDF's that you'd like to contribute. The PDF Library also includes all articles (1989-2019) published in the IAOS Bulletin.

IAOS SOURCE CATALOG REVIEWERS ARE NEEDED: While we continue to maintain the IAOS World Obsidian Source Catalog, our knowledge of obsidian sources outside of the United States and Canada is sometimes incomplete or inaccurate. We would like to invite any regional obsidian source specialists to have a look at the Source Catalog and get back to us (see the email address above) if you spot any problems. We'll be happy to acknowledge your participation and we'd like to thank Dr. Maria Victoria Fernandez for her help in sorting out sources in Patagonia (Argentina and Chile), South America.

PLANNING AHEAD FOR THE 2021 INTERNATIONAL OBSIDIAN CONFERENCE: Hosted by the International Association for Obsidian Studies (IAOS), the Archaeological Research Facility (ARF), and Far Western Anthropological Research Group (FWARG), this three-day event will be held at the University of California - Berkeley, from April 10-13, 2021. Details are HERE.

TWENTY-FIVE YEARS ON THE CUTTING EDGE OF OBSIDIAN STUDIES: Edited by Carolyn Dillian, this volume of selected readings from the IAOS Bulletin is still available for online ordering at $10 per copy (plus postage). Click HERE for a sample and all the details on how to instantly order your copy. For a review (PDF) of the book, click HERE.

TAKE CARE OF YOUR MEMBERSHIP DUES ONLINE: We have a membership payment option that is run through PayPal. Click HERE for the details.

IAOS EXTRAS: Be sure to have a look at the IAOS Extras page for some obsidian-related tools and resources that fall into their own unique category. These include several obsidian hydration-related tools and documents put together by Sandy Rogers and, most recently, a spreadsheet listing of obsidian references assembled by Chris Lloyd (updated 06-12-2019). This reference spreadsheet now contains over 5,000 literature references.
