Geochemical data treatment and interpretive uncertainty
On Sourcing Stonehenge Sarsen Stone #58
This is a brief response to Nash and Ciborowski's comments in 2025 on our 2024 paper, which focused on the reinterpretation of geochemical data for Stonehenge stone #58 published by Nash et al. in 2020. We address the problems they perceived in our use of absolute elemental concentrations, our selection of discriminating elements, and single‐sample comparisons and show the limited relevance of their arguments to our conclusions. We maintain that …
Justification for reassessing elemental analysis data of ceramics, sediments and lithics using rare earth element concentrations and ratios
The mensuration of multi‐elemental concentrations from assorted archaeological materials has always required great care and attention to detail to ensure good‐quality data and their ensuing interpretations. Although most suspect data were generated before the wide use of computers, error‐free data are not still a certainty. This paper presents the geochemical rationale for a proposed chemical data‐assessment process, using a globally dispersed co…
Tracing the Distribution of Late 16th and Early 17th Century European Copper Artefacts in Southern Québec and Ontario, Canada
To understand the nature of trade/exchange of ‘Basque’ copper kettles and their fragments among Indigenous communities from Québec to Ontario, Canada, we examined 948 copper samples from 75 archaeological sites. We found that 936 samples were sortable into 11 coarse chemical groups: seven biased towards Ontario, three favouring Québec and only one balanced between the two provinces. This pattern may represent kettles and pieces ‘mostly traded’ or…
Archaeometry at Slowpoke‐toronto
This paper describes the archaeometric research conducted at the SLOWPOKE Reactor Facility of the University of Toronto (SLOWPOKE‐Toronto) during its existence from 1971 to 1998. The contributions to student teaching and research are described, and the total contribution of the facility to studies of an eclectic assortment of ancient and historic materials is addressed

The Adaptive Significance of Geophagy for Japanese Macaques (Macaca fuscata) at Arashiyama, Japan
Chemical Analysis of 17th‐century Red Glass Trade Beads from Northeastern North America and Amsterdam
Seventeenth‐century opaque red (redwood) glass trade beads of different shapes and sizes were made of mixed alkali (mainly soda)–lime glasses and were coloured with Cu, presumably as cuprous oxide or as finely dispersed elemental Cu. During the early 17th century, beads of all shapes were opacified with Sn; cored beads, with uncoloured cores and hence lower Cu levels, also tended to have slightly lower Sn contents than uncored beads. By the mid‐1…

Geochemistry and clay mineralogy of termite mound soil and the role of geophagy in chimpanzees of the Mahale Mountains, Tanzania
Geophagy of Holstein Hybrid Cattle in the Northern Andes, Venezuela
During the course of a Quaternary stratigraphic reconnaissance of the northern Venezuelan Andes, W. C. Mahaney and M. Bezada observed Holstein hybrid cattle consuming reddish-brown soil formed in residual regolith from bedrock outcrops (Figure 1). In all cases, the source sites of the eaten soils were located above 3,000 m a.s.l. in the Venezuelan paramo. While there are a number of such sites, only one was sampled to characterize mineral composi…

Neutron Activation Analysis of Ad 1660–1930 European Copper‐coloured Blue Glass Trade Beads From Ontario, Canada
Blue glass trade beads from well‐dated late seventeenth‐ to early twentieth‐century sites and collections have been analysed non‐destructively by instrumental neutron activation analysis. The beads display enough variations in their elemental contents to allow us to characterize the different chemistries. The implication of these results is that similar chemical analyses of blue beads from undated archaeological sites may be used to help date the…
