DOCUMENT Citation Only Tawny Tibbits. Ellie Harrison-Buck. Terry Powis.

Portable x-ray fluorescence (pXRF) is a rapidly spreading yet controversial technology in archaeology. Current research on pXRF technology has produced marked improvements in calibration standards and accuracy of results. Previous studies using pXRF have focused primarily on obsidian and basalt; however with current advances in technology it is possible and necessary to test the applicability of pXRF to accurately characterize heterogeneous materials. This research proposes a methodology for...
