“…A crucial point for a reliable identification of the origin of the metal is the interpretation of the lead isotopic data. In fact, this step is carried out by reasoned comparison with an extensive database containing both geochemical and isotopic data of mineralizations of the Mediterranean area, developed over the years by the AAcP project (Alpine Archeocopper Project, 2022), and integrated by the most relevant data available in the literature (OXALID, 2018;BRETTSCAIFE, 2022;Ling et al, 2014;Nimis et al, 2012;Nimis et al, 2017;Artioli et al, 2016;Artioli et al, 2020;García De Madinabeitia et al, 2021;Tomczyk, 2022). As previously discussed, the reliability and good results of the method have been demonstrated by several studies recently carried out both on metal finds and on ores (Nimis, 2010;Artioli et al, 2017;Canovaro et al, 2019).…”

“…However, many regions only have a weak coverage for copper (let us quote for example the case of France for which the majority of the studied deposits concern lead-zinc and not copper). A postulate of standardisation, rationalisation, and making existing datasets publicly available has recently been discussed by G. Artioli and co-authors (Artioli et al, 2020: 23) and various open-access databases are currently under development, such as the aforementioned GlobaLID (see also a recently published database by C. Tomczyk, Tomczyk, 2022).…”

This paper discusses the applicability of the Principal Component Analysis-Agglomerative Hierarchical Clustering (PCA-AHC) approach to provenance studies of non-ferrous metals using combined Pb isotope and chemistry data. Pb isotopic ratios were converted to the natural abundance of individual isotopes and then to weight units. Next, all relevant variables (Pb isotopes and trace elements) were processed with PCA and AHC to examine the relationships between observations. The method is first verified on three literature-based case studies (1, 2, and 3). It is argued that, as is the case in archaeological iron provenance studies, the PCA-AHC method is also viable for non-ferrous metals. This method can greatly facilitate research, compared to conventional biplots with ratios of Pb isotopes and trace elements. Additionally, PCA-AHC can become part of the initial deposit selection process, and it can help clarify less obvious classification cases. The main problem with a practical application of this approach is insufficient deposit datasets with complete Pb isotopic and chemistry data. In such cases, it is possible to use the PCA-AHC method separately on Pb isotopic and chemistry data and then to compare and contrast results. Alternatively, the proposed approach can be used solely with Pb isotopic data. This application is shown in two additional case studies (4 and 5), which demonstrate the method’s application for tracing artefacts to their parent ores using datasets with a few thousand observations.
