From: Quantitative assessment of Pb sources in isotopic mixtures using a Bayesian mixing model
(a) Map of eastern Europe outlining the location of the Romanian artefact (Litharge roll, black circle). Also displayed are all mining regions modelled to understand the provenance of the Pb within the artefact. (b) displays convex hulls for modelling the litharge roll, Romania. As before, black circles reflect the sources used to reconstruct possible sources of Pb, whilst the green cross indicates the isotope composition of the modelled artefact.
