Additional file 1 of The origin of lead artifacts from Novae: applications of Pb isotopes in identifying the provenance of Roman artifacts from N. Bulgaria

Additional file 1. Table with the results of Pb isotope analyzes for lead samples from Novae and literature data for comparison and determination of provenance. The tables also present results for the calculation of Euclidean distances between samples from Novae and lead ore data from individual deposits. Distances indicating a good match are marked in red, and distances indicating a slight match are marked in yellow. No color means no match.
