Geoarchaeology Laboratory, UH Hilo
UH Hilo archaeologist Dr. Peter Mills founded the Geoarchaeology Laboratory in 2004 through a Major Research Instrumentation Grant from the National Science Foundation (BCS-0317528). Mills had been introduced to non-destructive Energy-Dispersive X-Ray Fluorescence (EDXRF) sourcing of obsidian during his graduate work with Dr. M. Steven Shackley at U.C. Berkeley. After Mills arrived at UH Hilo, he proposed the idea of acquiring EDXRF technology to geologist Dr. Ken Hon, who signed on to Mills's NSF proposal as a co-PI to help promote applications in geology as well as archaeology. Shortly thereafter, geologist Dr. Steve Lundblad joined with Mills while Hon moved into other roles.
Mills and Lundblad have operated the lab as inter-departmental collaborators for almost two decades, and have helped train many undergraduates and several graduate students in EDXRF technology. By 2004 archaeologists regularly used EDXRF for obsidian analyses, but the UH Hilo Geoarachaeology Lab vastly expanded applications to non-destructive analyses of more hetergeneous artifacts made of basalt, trachyte, and andesite. The lab has also re-introduced the value of this analytical technology to the geological community, where rapid analyses of fresh eruptive material can be of great benefit.
Mills and Lundblad have funded the lab with 2 additional NSF grants (BCS-0949058 and BCS-1427950), and maintain a university account to cover laboratory costs such as equipment maintenance. End-users include a multitude of archaeologists working in the Pacific (see publications below) as well as geologists such as Dr. Cheryl Gansecki who have relied on the lab for near real-time geochemical analyses of ash, pressed-pellet samples and whole rock from the 2018 Kīlauea eruption and the 2022 Maunaloa eruption.

We currently expend over $10,000/year to maintain a service contract on the EDXRF spectrometer and must charge fees through a Research Corporation of the University of Hawaiʻi (RCUH) revolving account for outside analyses to help cover these costs. For analyses not related to the current NSF Grant, our standard fee for clean basalt samples is $30/sample, but we regularly negotiate subsidized rates for large submissions and student research. Our philosophy is that it is in everyone's best interest to analyze large numbers of samples rather than to have researchers submit fewer samples due to tight budgets.
