AbstractIt is to be expected that drift will occur in the energy calibration of Energy Dispersive X-Ray Fluorescence Analysis (EDXRFA) spectrometers. The error thus caused in the measured x-ray intensity is evaluated in this paper. In order to minimize the error, two steps are necessary. The first is to make a new energy calibration to follow the trend of the drift. The second step involves moving the regions of the characteristic peaks to accommodate the drift. Software has been developed to accomplish both steps automatically.

AbstractThe use of energy-dispersive X-ray fluorescence analysis (XES) for the routine identification of three tephras (Mazama, Bridge River, Mount St. Helens Yn) commonly found in archeological sites in British Columbia has been investigated. Researchers have often assumed that chemical analysis of bulk samples of glass separates would be hampered by contamination and weathering effects. Our results indicate that XES of bulk glass separates provides a very reliable method for rapidly identifying the three tephras in question, even with a very simple sample preparation. This should enable persons not skilled in geology or in tephrochronology to collect and to identify samples of these tephras. Finally, as a part of the study, similar measurements were made on the separated glass portions of these three tephras and of three others (Glacier Peak B and G, White River) from northwest North America. The results suggest that this method may provide tephrochronologists with a useful additional tool for studying tephras in other regions.
