“…The EAF is currently working on generating an improved calibration for mafic rocks using multiple pelletized USGS rock standards that better bracket concentrations for basalts. However, our results are internally consistent, and the patterns noted in our samples hold whether considering calibrated results or Comptonnormalized peak heights (e.g., Grave et al, 2012).…”

“…In other areas of the world, XRF analyses of basalts have generated enlightening results (e.g. Grave et al, 2012;Lundblad et al, 2008;Mills et al, 2011) and suggest that similar projects elsewhere might enjoy comparable success.…”

“…A major advantage of pXRF is that instruments can be transported to study objects in situ, thereby permitting multi-element analyses of archaeological materials in non-traditional laboratory environments. However, archaeological applications of pXRF are still today an object of discussion (Liritzis, & Zacharias, 2010;Tykot, et al, 2013), principally because of a perceived lack of analytic rigour (Shackley, 2010(Shackley, , 2012Grave, Attenbrow, Sutherland, Pogson & Forster, 2012;Speakman & Shackley, 2013;Frahm & Doonan, 2013). The present work contributes to this debate regarding pXRF through the study of Caltagirone pottery raw materials.…”

Abstract:In the study of archaeological ceramics, it is important to have compositional data to identify their origin and source. The fabric also provides useful information on the production technology, especially with regard to the firing steps. The work presented here is connected to this field and focuses on the main parameters related to the terracotta artefacts preparation. Thus, one can consider the effects in terracotta characteristics of different raw materials and firing parameters, in particular for pottery of Caltagirone, which is one of most important centres of pottery production in Italy, active since the Neolithic. To this end, terracotta samples have been reproduced in a laboratory setting according to the ancient procedure of Caltagirone manufacture, starting from clay and degreaser extraction in local historical sites. The analysis was conducted using a portable X-Ray Fluorescence (pXRF) spectrometer for elemental characterization of sand degreaser and of clays during each step of the realization process and in different firing conditions. SEM-ED techniques were also employed to verify the method and results for some of the samples after firing process. Framing the technological context of manufacture production, known in the specific case, it is also possible to identify potential outcomes and limits in the study of potsherds using pXRF technology, in applying the methodology to historic artefacts.

“…While such criticisms are valid and should be considered carefully when designing PXRF-based studies, it should also be noted that different research questions and materials may require different analytical approaches and different units of measurement (e.g., Grave et al, 2012Grave et al, : 1676. Quantitative values are critical in some applications, such as obsidian provenance analysis.…”

Portable x-ray fluorescence spectrometry was used to chemically source Busycon shell items from three eastern Tennessee Mississippian period sites. Discriminant function analysis of portable x-ray fluorescence data from control shells from the Atlantic and Gulf coasts indicated variation in strontium levels in Busycon provides a statistically significant predictor of shells' origins, correctly classifying 86.5% of controls to their coasts of origin. Application of the discriminant function to shell items from Mississippian sites in northeastern and southeastern Tennessee indicated significant differences by region in proportions of artifacts classified as deriving from Atlantic or Gulf coast shell. More than 60% of items from southeastern Tennessee exhibited strontium levels similar to Gulf coast control shells; less than 50% of northeastern Tennessee items were classified as deriving from the Gulf. Variation in ratios of Gulf-to Atlantic-sourced shell artifacts by region is consistent with past predictions that late prehistoric inhabitants of southeastern and northeastern Tennessee participated in different long-distance exchange networks.
