Authentification of Ancient Bronze Coins by the Study of the Archeological Patina.I.Composition and Structure

摘要

This paper presents comparative results concerning the chemical composition and mineralogical distribution of the main compounds from the structure of the archaeological patina of ancient bronze coins,which were determined by the corroboration of microchemical,IR spectrophotometry,SEM/EDAX and termogravimetric methods.The distribution of the chemical components in the stratigraphic structure is determined by the pedological processes from the archaeological sites and which represents main elements used in the authentication of ancient bronze artifacts.
