%X Le tracce di ossidiane e la caratterizzazione delle componenti chimiche presenti nei luoghi oggetto di indagini archeologiche, permettono l'individuazione delle antiche rotte commerciali. In Italia le aree individuate sono Monte Arci in Sardegna, Lipari e Pantelleria in Sicilia e Palmarola nel Lazio.   Obsidian  from  Palmarola:  source  markers A  chemical  characterization  of  the  main  components  and  traces  of  obsidian  allows identi  cation  of  commercial  routes  in  antiquity.  Obsidian  sources in Prehistoric Italy were mainly four: Monte Arci in Sardinia, the islands of Lipari and Pantelleria in Sicily and the island of Palmarola in Lazio. A survey methodology on samples of obsidian from several Neolithic sites in Lazio has been developed, comparing three different analytical techniques: SEM-EDS, XRF and LA-ICP-MS, in order to obtain a wider range of data to be compared with literature records and processed by Principal Component Analysis (PCA), to de  ne relationships between samples and to assign each  nding its origin.
