The importance of these beads is due to the fact that they are possibly among the earliest lapis lazuli objects found in south-eastern Arabia to date. The combined results of the provenance and stylistic investigations presented in this work aim to assess the geological origin of the raw material used to produce these beads as well as their cultural affiliation, providing crucial insights into reconstructing the lapis lazuli trade between Western Asia and the Mediterranean during the third millennium BCE. To identify the lapis lazuli provenance, in-air ion microbeam techniques were used to measure the trace elements content and the luminescent properties of different mineralogical phases within the lapis lazuli rock. Data were compared with those collected over the past 15 years on rocks from five mining areas in Chile, Afghanistan, Siberia, Tajikistan and Myanmar.

Although they are non-alloyed artifacts, it has been demonstrated recently that the Pb in most tin ingots was acquired from multiple sources. Herein, we re-examine the corpus of analytical chemical and isotopic studies of European tin ingots from prehistory to investigate the nature and extent of metal mixing in these objects. Multi-variable mixing trends were identified in 20% of Uluburun ingots and 50% of Israeli ingots. A general Pb-associated mixing trend observed throughout the full assemblage of oxhide ingots in the Uluburun cargo suggests that the extent of mixing is considerably higher. The absence of mixing patterns in Sn and Pb isotopes and small size of the ingots from SW England suggests simple one-pour casts of small ingots. In contrast, the extensive mixing in large Mediterranean ingots demonstrates that amalgamation and recasting of tin metal was commonplace within this region of extensive long-distance exchange. Mixing trends were also identified for trace elements including Mn, Co, Ni, Cu, Zn, As, Se, Nb, Cd, In, Sb, Te, Ta, Au, and Bi. The complex mixing patterns associated with Mediterranean tin ingots provide new information regarding the <em>habitus</em> of workers engaged in the <em>chaîne opératoire</em> of tin production, including ore purification, contamination during smelting and/or casting, and the recasting of tin to facilitate transport and exchange in the large-scale, standardized markets of the eastern Mediterranean. Given the apparent extent of mixing evident in tin ingots, mixed metal sources must be considered when interpreting the isotopic and trace element compositions of tin artifacts to infer the metal's provenance.</div></div>","PeriodicalId":50254,"journal":{"name":"Journal of Archaeological Science","volume":"174 ","pages":"Article 106135"},"PeriodicalIF":2.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142874772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Marble provenance studies contribute to a better understanding of the economy and the societal structure of the area and may serve as a model for other larger-scale research of local quarries and ancient sites, as well as the connections and the long-distance trade and sub-regional/regional marble markets. The case study of Philippopolis (mod. Plovdiv, Bulgaria) projects the phenomenon of ‘localism’ by prioritising the local raw material, the local production and consumption of goods. However, on certain occasions, the province kept its connectivity with large marble producers of the Eastern Mediterranean, such as Prokonnesos, Aphrodisias, Penteli, etc., for specific artefacts (e.g., sculptures). Employing a diverse array of methodologies, including stable isotope analysis (C13 and O18), multi-trace element analysis through ICP-MS, and petrography, enables the identification of the provenance of these samples. This study entails a deeper exploration of the relationship between producers and resources, as well as the historical evolution of marble consumption patterns in the area.

However, most archaeological research has focused on individual routes at specific periods, and little has been done so far to research road networks' long-term evolution at a regional scale. While the widespread availability of high-resolution aerial imagery facilitates recording ancient road networks in details, their chronological diagnostic remains challenging since road architecture is generally not a reliable proxy and direct stratigraphic dating is limited to very few contexts. This paper outlines a modelling approach to assess the chronology of roads based on their topological relationship with dated settlements, an idea formulated long ago but never technically implemented so far. It presents a case study on a regional road network's evolution during the last millennium, in the arid highlands of northern Chile, which conserve abundant traces and infrastructure of the settlement patterns and movement systems of its ancient territories. The case study shows the potential of this predictive modeling approach to preliminarily assess the chronology of individual road segments, as well as to visualize and characterise the evolution of the whole network through the historical periods. The basic models implemented in this paper to derive probabilities could be further refined for more specific contexts and hypotheses, and applied to many deserts and mountain regions worldwide, where ancient roads and pathways frequently accumulate as part of long-term territorial dynamics.</div></div>","PeriodicalId":50254,"journal":{"name":"Journal of Archaeological Science","volume":"174 ","pages":"Article 106125"},"PeriodicalIF":2.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142825109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reflectance spectra and CIE color parameters indicate that the optimal synthesis temperature for Maya blue lies between 100 and 200 °C, with a recommended heating time not exceeding 8 h. Increasing the temperature (up to 200 °C) enhances the green hue while diminishing the blue hue; however, temperatures above 200 °C result in significant color saturation loss. At 150 °C, extending the heating duration increases the green hue while maintaining stability after 8 h, with a corresponding reduction in the blue hue. The specific surface area, micropore volume, and X-ray diffraction results suggest that indigo molecules diffuse deeply into the palygorskite channels under heating. The infrared spectra indicate that the interaction between indigo and palygorskite appears weak, with indigo being encapsulated as stabilized monomers through intramolecular hydrogen bonding, which contributes to the greenish-blue hue and exceptional stability of Maya blue. High-resolution transmission electron microscope images confirmed the identical microstructure of Maya blue and raw palygorskite.
