Abstract: | Pb isotopic analyses on metal artifacts help constrain their provenance. Useful and reliable data require analytical protocols
that ensure accuracy and monitor precision. The interpretation can sometimes be ambiguous because natural ore deposits frequently
have overlapping Pb isotopic compositions. In most cases, however, provenances can be reliably narrowed down. For the Alpine
region, a pattern of small, strongly localized mine exploitations in pre-Roman times, supplemented by some long-distance trading,
is taking shape. |
