Current Research: A Pilot Study in the Use of pXRF Analysis of Caddo Ceramics

Wilson "Dub" Crook III's paper presented to the East Texas Archeological Conference concerning the use of X-ray Fluorescence (XRF) in sourcing turquoise artifacts sparked an interest in utilizing pXRF to resolve an old Caddo ceramic research question. While XRF has been used in archaeology for more than 60 years, and there have been applications in ceramic studies, a recent review of the 9th Edition of The Archaeology, Bioarchaeology, Ethnohistory, and History of the Caddo Indian Peoples of Arkansas, Louisiana, Oklahoma, and Texas, a comprehensive bibliography, did not yield a single reference to a pXRF study in Caddo ceramics. This article will summarize: (1) the research question arising from work at the Morse Mound Site (41SY27), (2) an overview of how pXRF works, and (3) the data analysis from this pilot study.
