The potential of obsidian "big data"

UISPP Journal, 2019
Studies of obsidian provenance have been a core component of the archaeological sciences from the mid-1960s onward. With the growing application of portable X-ray Fluorescence Spectrometers (PXRF) in obsidian research, the number of such studies, and the

The Geoarchaeology of Agricultural Terraces in Europe: Construction, Resilience and Implications for Sediment Delivery

Geoarchaeology, Volume 40, Issue 2, March/April 2025.
ABSTRACT Although the primary purpose of agricultural terracing can be assumed to be food production, it has been suggested that a secondary purpose was the control of soil erosion. In this paper, we explore this thesis with multi‐proxy data from the TerrACE project, which studied 20 sites in a latitudinal transect across Europe.

Advancing Leaf Nutritional Characterization of Blueberry Varieties Adapted to Warm Climates Enhanced by Proximal Sensing

AgriEngineering
Blueberries offer multiple health benefits, and their cultivation has expanded to warm tropical regions. However, references for foliar nutritional content are lacking in the literature.

Investigating Technological Changes in Copper-Based Metals Using Portable XRF Analysis. A Case Study in Sicily

Open Archaeology, 2017
The introduction of copper-based metals in Sicily appears to have been a particularly late and slow process. A program of pXRF analyses on early metals in Sicily has revealed the use of mostly copper, and a very late introduction of tin.

Late Holocene Evolution of the Lagoonal Harbour of the Punic Centre of Othoca (Western Sardinia, Mediterranean Sea)

Geoarchaeology, Volume 40, Issue 2, March/April 2025.
ABSTRACT Geophysical surveys and multiproxy analyses of sediment cores have been used to reconstruct the palaeoenvironmental evolution of the Santa Giusta coastal lagoon (SGL), along the western coast of Sardinia. This area served as a natural harbour mainly during the Punic and Roman Republican periods (6th–2nd century bc).

On‐Site Raman and XRF Study of Complex Metal Patinas and Cloisonné Enamels From 19th‐Century Christofle Masterpieces: Technological Study of the Decoration Techniques

Journal of Raman Spectroscopy, Volume 56, Issue 3, Page 243-261, March 2025.
A major effort in technological development was conducted during the 19th century. The polychrome surfaces of the metal and enameled parts of artifacts made between 1874 and 1878 for Christofle & Cie were analyzed on site by means of noninvasive Raman, FTIR, and X‐ray fluorescence spectroscopy. Pigments, opacifiers and (electro)chemically formed phases

Economic space: On the analysis and interpretation of pottery production and distribution [PDF]

, 2016
Ceramics are particularly well suited for investigating general patterns of the distribution of premodern products. Archaeometric methods, used to determine raw materials and production techniques, permit the identification of places of production.
