Original Paper


The voltammetry of microparticles (VIMP) methodology was applied to a set of submicrosamples from the corrosion layers of copper artifacts from the archaeological site of La Vital (Gandia, Spain), dated back to 4200 to 3900 BP, attached to graphite electrodes in contact with aqueous acetate buffer at pH 4.50. Signals for the reduction of cuprite plus malachite, dominating the composition of the corrosion layers, and tenorite, were used for grouping the samples. A model to describe their relative concentrations assuming gradients following a potential law is proposed and tested with experimental data. Correlation of VIMP sample grouping with lead isotope data in literature permitted to discriminate archaeological samples depending on the provenance of raw materials and the manufacturing process.
