Observations on sample size for lead isotopic analysis of ancient copper alloys
Key Points
The research aims to identify the heterogeneity of lead isotope ratios in ancient copper alloys on a micro-scale.
Analyzed lead isotopic variations in copper alloys at micro-scale.
Recommended minimum sample mass to produce representative results.
Identified significant micro-scale heterogeneity in lead isotope ratios.
Proposed specific sample mass thresholds to minimize non-representative findings.
Abstract
This paper identifies potential heterogeneity of lead isotope ratios on the micro-scale in (ancient) copper alloys, and recommends minimum sample mass to avoid non-representative results.
