Welcome to the Northwest Research Obsidian Studies Laboratory website. We offer a variety of different analytical services related to obsidian artifact trace element provenance ("sourcing") studies and obsidian source studies, primarily in the context of archaeological research. This website describes our services and provides methodological and source information that supplements and supports our contract investigations and research interests.

THE XRF LAB IS CURRENTLY CLOSED UNTIL AUGUST 1, 2014

The XRF laboratory is completely closed this year from January 1st, 2014, to August 1st, 2014, and we are not accepting any new projects until we reopen again. Click HERE for the rest of the details. Looking for obsidian hydration analysis services? Our former obsidian hydration laboratory is now Willamette Analytics and will remain open for business in 2014 while the XRF lab is temporarily closed.

THE XRF LAB IS TEMPORARILY CLOSED: It's been many years since I last took a substantial break and I'll be using the first half of 2014 for that opportunity. From January 1, 2014, through August 1, 2014, the XRF lab will be closed. Click HERE for more recently updated information.

UPCOMING WEBSITE MAKEOVER: You may have noticed that the lab website has been pretty static lately and that we've been woefully slow to update some sections. Truth is, we've been exceptionally busy over the last year. Plans for 2014 include some serious website restructuring, restoration, and rebuilding.

EXPANDED ONLINE OBSIDIAN SOURCE RESOURCES: As time allows, we've been gradually expanding the source descriptive and literature reference information at the U.S. Obsidian Source Catalog. This project is still rough around the edges but you can see where we're going with it by looking at the SOURCE INFORMATION menu located to the left. Click HERE for more information.

THANKS AND A TIP OF THE HAT: We just celebrated 18 years as Northwest Research and the continued success of a small analytical laboratory like ours would simply not have been possible without the help and interest of a lot of different people over the years. For all of you that have helped along the way ... thanks!.

UPDATED DOWNLOADS: We've reorganized the lab downloads and have relocated most of the obsidian-related articles, reports, theses, and dissertations to the new IAOS PDF Library. Our standard lab forms and other lab docs can still be found HERE.
