This paper thematically characterizes a large body of recent obsidian sourcing discourse as
a means of highlighting the current place of obsidian provenance studies in larger …

The Lower to Middle Paleolithic transition (~ 400,000 to 200,000 years ago) is marked by
technical, behavioral, and anatomical changes among hominin populations throughout …

Uncritical application of portable X‐ray fluorescence (PXRF) to non‐destructive analysis of
archaeological ceramics has been received with scepticism. In this article, we present a …

The physical requirements of stone tools tend to prescribe the choice of rocks for their
production. Hardness, roughness and impact toughness dictate the ease of knapping as …

Handheld portable XRF (HHpXRF) has received considerable recent attention in
archaeology, especially for obsidian sourcing. Published studies largely suggest a high …

Portable X-ray fluorescence (pXRF) has been demonstrated as a powerful tool to assign
obsidian artifacts to sources. Newer instruments can even match artifacts from some regions …

This article demonstrates the accuracy of non-destructive portable X-ray fluorescence
(pXRF) for the study of obsidian in central Mexico. Obsidian sources were identified for a …

The scope of this chapter is the application of handheld portable energy-dispersive X-ray
fluorescence spectrometers (commonly referred to as portable XRF (pXRF; p-ED-XRF) …

The aim of this study is to estimate the uncertainty of a portable X-ray fluorescence (p-XRF)
instrument for the (semi-quantitative) analyses of tiles with underglaze decoration. Before …

Non-destructive pXRF has the potential to expand sample populations of archaeological
provenancing studies by facilitating access to museum collections of artefacts. In this study …
