The results of a study on 111 obsidian artifacts collected during an archaeological campaign performed by the University of Siena near Sesto Fiorentino (Florence, Italy) are reported. Earlier, we used the concentration ratios among some elements as reported in the literature to discriminate the deposit sources. Later, optimizing the characterization and for having a more strong classification, multivariate chemiometric investigation has been performed (multivariate statistical analysis in Principal Components and Discriminating Factor Analysis). The data obtained show three wellseparated groups connected to the relative sites in Lipari and in Sardinia (flows A and C from Arci Mountain). © 2008 Springer Science+Business Media, LLC.
