Welcome to Northwest Research Obsidian Studies Laboratory

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, obsidian hydration analysis, and obsidian source studies, primarily in the context of archaeological research. We also provide nondestructive artifact characterization studies for fine-grained volcanic materials (including basalt) in the Lake Tahoe region of California and a few other selected geographic areas. This website describes our services and provides methodological and source information that supplements and supports our contract investigations and research interests.

U.S. Obsidian Source Catalog

OBSIDIAN SOURCE CATALOG TUNEUP BEGINS: We've begun adding additional basic information to the U.S. Source Catalog. The first state up for remodeling will be Utah, currently the home of several ongoing obsidian provenance projects.

Obsidian source maps

SELECTED OBSIDIAN SOURCE MAPS ARE NOW AVAILABLE: We're still working diligently at producing obsidian source maps for the western United States and are continuing to add to our collection on a regular basis. To see our latest additions, click HERE.

Fieldwork

SUMMER FIELD WORK: After a particularly productive 2009 field work season at the lab, we're anxious to see what we'll find in 2010 - click HERE for the details.
