锡在过去是一种重要的商品。在中欧，最早发现的锡青铜可追溯到公元前2200年左右，而在希腊，则是公元前2200年左右。400-500年前。虽然有证据表明史前时期有铜矿开采，例如在阿尔卑斯山或希腊大陆等地，但当代锡的来源仍然是一个未解决的问题。本文提出了一种利用锡同位素示踪古锡的新方法。采用MC-ICP-MS法测定了厄尔士山脉（D）50个锡矿和康沃尔（GB）30个锡矿的锡同位素组成。这一事实可以用来区分不同的锡矿床，从而为世纪以来一直在寻找的古代锡的来源的调查奠定基础。此外，锡同位素比的'Himmelsscheibe冯内布拉'将被提出：该值符合大量的调查锡矿石从康沃尔。（减）
Tin was a vital commodity in times past. In central Europe, the earliest finds of tin-bronze date to about 2200 bc, while in Greece they are c. 400-500 years earlier. While there is evidence for prehistoric copper mining-for example, in the Alps or mainland Greece, among other places-the provenance of the contemporary tin is still an unsolved problem. This work deals with a new approach for tracing the ancient tin via tin isotope signatures. The tin isotope ratios of 50 tin ores from the Erzgebirge region (D) and 30 tin ores from Cornwall (GB) were measured by MC-ICP-MS. Most ore deposits were found to be quite homogeneous regarding their tin isotope composition, but significant differences were observed between several deposits. This fact may be used to distinguish different tin deposits and thus form the basis for the investigation of the provenance of ancient tin that has been sought for more than a century. Furthermore, the tin-isotope ratio of the 'Himmelsscheibe von Nebra' will be presented: the value fits well with the bulk of investigated tin ores from Cornwall. (Less)
