“…The accuracy of the technique is well demonstrated (e.g., Higgins 1984, Gladney et al 1984, Vittoz et al 1987, Nabelek et al 1992, Leeman et al 1992). Further information on the PGNA A method applied to minerals is given in Robertson and Dyar (1996); a comprehensive review of the theory and analytical applications of PGNAA can be found in the works by Glascock et al (1985) and Lindstrom and Anderson (1985).…”

The quantitative determination of light element concentrations in geological specimens represents a major analytical challenge as the electron probe is generally not suited to this task. With the development of new in situ analytical techniques, and in particular the increasing use of secondary ion mass spectrometry, the routine determination of Li, Be and B contents has become a realistic goal. However, a major obstacle to the development of this research field is the critical dependence of SIMS on the availability of well characterized, homogeneous reference materials that are closely matched in matrix (composition and structure) to the sample being studied. Here we report the first results from a suite of large, gem crystals which cover a broad spectrum of minerals in which light elements are major constituents. We have characterized these materials using both in situ and wet chemical techniques. The samples described here are intended for distribution to geochemical laboratories active in the study of light elements. Further work is needed before reference values for these materials can be finalized, but the availability of this suite of materials represents a major step toward the routine analysis of the light element contents of geological specimens.

“…During this same time period, Michael D. Glascock (MDG), who joined MURR in 1979, was investigating archaeological applications for prompt gamma neutron activation analysis (PGNAA) to various matrices, including metals and obsidian (Glascock 1981; Glascock and Cornman, 1983; Glascock et al 1984). Methods for automating data collection in INAA and PGNAA, correcting for interferences from fission products and fast neutron reactions, and monitoring quality of the collected data were also established (Glascock et al 1985, 1986; Glascock and Anderson 1993).…”

Descriptions of the history of the Archaeometry Laboratory at the University of MissouriResearch Reactor and the procedures used for instrumental neutron activation analysis of archaeological materials are presented. The laboratory was established in 1988 to support students and faculty from the University of Missouri and other universities who were interested in archaeological research involving compositional analysis. The results obtained from the analysis of obsidian sources and artefacts from locations in the continental USA are presented for illustration.The proposal to build a research reactor on the University of Missouri (MU) campus was conceived in the late 1950s. The primary objectives were to stimulate scientific research and educational opportunities for MU faculty and students. Funds to build the reactor were appropriated by the Missouri State Legislature and approved by the Governor in 1959. Construction of the MU-Research Reactor (MURR) was completed and the reactor was in operation by the autumn of 1966. The choice of a flexible reactor design facilitated several expansions and upgrades over the years, to accommodate changing research needs and technological advances. Today, the MURR operates on a 150-hour per week schedule at a power of 10 MW and employs more than 140 full-time staff. The MURR supports research, education and service in a variety of disciplines, including (but not limited to) agriculture, engineering, medicine, epidemiology, chemistry, physics and archaeology.
