THE IDENTIFICATION OF THE SOURCE OF COPPER MINERALS USED FOR PREHISTORIC SMELTING IS A HOTLY DEBATED TOPIC IN MODERN ARCHAEOMETALLURGY. TO OVERCOME THE WELL KNOWN LIMITATIONS RELATED TO THE SOLE USE OF LEAD ISOTOPES RATIO AS TRACERS, AN EXTENSIVE PROJECT IS IN PROGRESS, WITH THE AIM TO (1) RE-INVESTIGATE THE MINERAL-CHEMISTRY AND GEOCHEMISTRY OF ALPINE COPPER DEPOSITS, (2) IDENTIFY THE USEFUL GEOCHEMICAL AND ISOTOPIC TRACERS, (3) DEFINE THE DISCRIMINANT MODELS OF THE MOST IMPORTANT ORE DEPOSITS BY ADVANCED STATISTICAL ANALYSIS, AND (4) SHOW THAT THE DEVELOPED MODELS CAN RELIABLY BE APPLIED TO THE SMELTING PRODUCTS: SLAGS AND UNALLOYED COPPER.

Abstract
THE IDENTIFICATION OF THE SOURCE OF COPPER MINERALS USED FOR PREHISTORIC SMELTING IS A HOTLY DEBATED TOPIC IN MODERN ARCHAEOMETALLURGY. TO OVERCOME THE WELL KNOWN LIMITATIONS RELATED TO THE SOLE USE OF LEAD ISOTOPES RATIO AS TRACERS, AN EXTENSIVE PROJECT IS IN PROGRESS, WITH THE AIM TO (1) RE-INVESTIGATE THE MINERAL-CHEMISTRY AND GEOCHEMISTRY OF ALPINE COPPER DEPOSITS, (2) IDENTIFY THE USEFUL GEOCHEMICAL AND ISOTOPIC TRACERS, (3) DEFINE THE DISCRIMINANT MODELS OF THE MOST IMPORTANT ORE DEPOSITS BY ADVANCED STATISTICAL ANALYSIS, AND (4) SHOW THAT THE DEVELOPED MODELS CAN RELIABLY BE APPLIED TO THE SMELTING PRODUCTS: SLAGS AND UNALLOYED COPPER. THE AVAILABLE DATA ON THE AGORDO AREA HAVE BEEN USED AS A TEST CASE FOR THE VALIDATION OF THE DISCRIMINATION MODELS.Pubblicazioni consigliate
