Isotope analysis is a flexible and powerful tool for provenance studies of archaeological objects. In the present study, lead isotopic analysis was used in order to gain insight into the origin of the mineral sources of coins minted in the Celtiberian mint of Turiasu and in six coloniae and municipia of the Conventus Caesaraugustanus (Hither Spain) under Augustus and Tiberius (27 BC-37 AD). In the case of Turiasu denarii, argentum from the Iberian Range mines was used, and in the Roman asses coined in civitates of the middle Ebro River, the copper minerals had a diverse origin (Pyrenean, from the Iberian Range, from the southeastern Iberian Peninsula and from the Central Iberian Zone). Differences in ore provenance and in bulk composition (investigated through X-ray fluorescence) were not only detected among the early Augustan, late Augustan and early Tiberian periods, but also among the mints under study. Moreover, differences were also detected among the mints of the Conventus Caesaraugustanus and the official mint of Rome, evidencing that the former enjoyed autonomy in terms of the choice of ore origin and processing.

同位素分析是用于考古对象物源研究的灵活而强大的工具。在本研究中，使用铅同位素分析来深入了解图里亚苏的Celtiberian薄荷以及奥古斯都和提比略下的西班牙凯撒格鲁古纳斯修道院（西班牙）的六个殖民地和市政的硬币的矿物来源。公元前27-公元37年）。在的情况下Turiasu银币，ARGENTUM使用来自伊比利亚范围矿山，并在罗马创造的驴在civitates在埃布罗河中部，铜矿物的起源多种多样（比利牛斯山脉，伊比利亚山脉，东南伊比利亚半岛和伊比利亚中部地区）。不仅在奥古斯丁早期，奥古斯丁晚期和泰伯利亚早期发现了矿石来源和散装成分的差异（通过X射线荧光研究），而且在所研究的薄荷糖中也发现了差异。此外，在Caesaraugustanus修道院的铸币厂和罗马官方铸币厂的铸币厂之间也发现了差异，这表明前者在矿石来源和加工选择上享有自主权。
