The first section addresses the issues surrounding highly radiogenic lead (HRL) from the Shang period, arguably the most widely discussed topic in Chinese bronze provenance research. In addition to providing an overview of the current discourse, this section emphasizes two critical questions: the metal(s) with which HRL is associated, and the meaning of its isochron-like trend line. Clarifying these questions could fundamentally alter our understanding of HRL and the metal circulation systems of the Shang period. The second section focuses on the emerging pattern in the rapidly growing body of publications on lead isotope analysis of Chinese bronzes, particularly the synchronic alteration of lead isotope features across vast regions over two millennia. Additionally, this section reviews specific spatial-temporal units, which have generated significant research in recent years and may reveal distinct metal circulation systems. The following sections shift attention to the provenance of copper and tin, essential components in the production of bronze artefacts but often overlooked in provenance studies. Methodological challenges are discussed, with a particular emphasis on the widely used trace element analysis technique. Furthermore, increasing archaeological evidence from metallurgical workshops related to mining, smelting, and alloying practices of these metals holds potential to shed new light on these issues in the near future. Finally, the review offers a brief discussion on model-informed provenance investigations, reflecting a global trend in the field, which is expected to have a substantial impact on the study of Chinese materials in various ways.</div></div>","PeriodicalId":50254,"journal":{"name":"Journal of Archaeological Science","volume":"180 ","pages":"Article 106272"},"PeriodicalIF":2.6,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144166369","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}

This method normalizes metric data using the Logarithm Size Index (LSI) scaling technique. LSI values of post-crania metric data of modern wild sheep from Iran and Iraq are shown to reflect strong sexual dimorphism in body size which is evident in animals over one year of age. After adjustments to account for the impacts of region and age on body size, along with differentials in the scaling of different elements, the mid-point of the range of LSI values is shown to be a reliable and accurate way of distinguishing between the elements of females and males that can then be used to construct sex-specific age profiles. This method is applied to metric data from thirteen archaeological sheep skeletal assemblages from the Zagros Mountains of Iran and Iraq spanning the period from the Middle Paleolithic to the Ceramic Neolithic. The resulting sex-specific demographic profiles indicate that during pre-ceramic periods hunters practiced varied prey strategies that targeted different segments of wild sheep populations. A clear signal of herding is detectable in Ceramic Neolithic assemblages despite limitations in the recovery of unfused elements.

Despite its effectiveness, this method encounters challenges in dating young archaeological sites in the Holocene period, such as stratigraphic disturbances, insufficient bleach, and residual doses from infrared stimulated luminescence (IRSL) of potassium-rich feldspar (K-feldspar), which compromise the accuracy of the dating results. To address the challenges of optical dating in young archaeological sites and to demonstrate its accuracy, this study applies diverse luminescence dating techniques at the Holocene archaeological site of Zhuqiusi in the Central Plains of China, with a specific focus on accurately dating pottery and sediment samples. For fine-grain (FG) quartz samples from pottery, single-aliquot regenerative-dose (SAR) OSL dating and multiple-aliquot additive-dose (MAAD) thermoluminescence (TL) dating methods were used. For coarse-grain quartz and K-feldspar from sediments, the SAR-based OSL method was used for quartz and the multiple-elevated-temperature post-infrared IRSL (MET-pIRIR) method was used for K-feldspar; in both cases, multi-grain (MG) or single-grain (SG) measurement protocols were adopted to investigate the effect of bleaching on dating. The results showed that the quartz OSL and TL ages of pottery samples were consistent, while sediment quartz and K-feldspar showed varying degrees of insufficient bleaching, leading to significant age differences. For such samples, single-grain dating methods must be used to obtain accurate luminescence ages. Ultimately, the Zhuqiusi site was dated to two occupation stages: the Eastern Zhou Dynasty (2.14–2.82 ka) and the late Longshan period (3.90–4.27 ka), consistent with radiocarbon ages within the error range.

Because the curved perimeter wall of the <em>cavea</em> was not able to withstand the lateral earth pressure on its own, Roman engineers started experimenting with reinforcement systems which led to a variety of different <em>cavea</em> substructures. One of the most innovative and intriguing solutions to this problem can be seen in the theatre of Augusta Raurica (present-day Augst, Switzerland) where the retaining walls of the theatre were reinforced by series of semicircular buttresses. In the almost identical theatre of Aventicum (Avenches, Switzerland) the more traditional solution of a system of radial and annular walls were used for the same purpose. To get a better understanding of the structural behaviour of the theatre in Augst, the <em>cavea</em> substructure of both the theatres of Augst and Avenches were analysed with finite element method (FEM). Contrasting the structural properties and the amount of building material needed for each of the two theatres shed light on some of the reasons why the unconventional solution utilized in Augst did not become common. Although it used less building material, it was not as robust as the structural solution used in Avenches. Also, the support for the long, rectangular limestone blocks of the seating were not sufficient in Augst and the seats might have been subject to a considerable uneven sinking as the earth infill under them consolidated and shrank.</div></div>","PeriodicalId":50254,"journal":{"name":"Journal of Archaeological Science","volume":"180 ","pages":"Article 106273"},"PeriodicalIF":2.6,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144115131","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}

There was no enrichment of Zn at the OES in enamel not yet matured (less than 33–37 postnatal days), suggesting that initial zinc incorporation is overshadowed by further deposition during maturation.</div><div>Diagenetic alteration of the Fe, Mn, Cu, and Ba elements in deciduous incisor enamel appears to affect their concentration in regions of the archaeological teeth. The observed Ca and Zn distribution pattern reflects distinct enamel maturation stages, highlighting the need to consider both diagenetic influences and developmental processes in trace element analyses of ancient dental samples.</div></div>","PeriodicalId":50254,"journal":{"name":"Journal of Archaeological Science","volume":"180 ","pages":"Article 106274"},"PeriodicalIF":2.6,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144106438","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}
