Alloying elements as chronotechnological marker for second and first century BC fibulae from ancient Pannonia

Fibulae as main the metal elements of people's costume and clothing vary significantly in form and shape through time, and therefore, they are the perfect chronological markers of periods and time horizons and help archaeologists to date associated finds and stratigraphic units precisely. Five Late La T\uc3\ua8ne fibulae (150-80 BC) typical of the Western Carpathian Basin were studied in order to achieve information of their composition and manufacture. In particular, the alloy compositions were analyzed to understand if different alloys were used for the bow and the pin of the fibulae, and to establish if Pb and Zn were present. The latter was introduced to the workshops in Gallia and Northern Italy, and reached as imports the southeast Alpine region around 50 BC, creating a chronological horizon interesting for dating. Pb with>5 wt.% also turned out to be a chronological marker of La T\uc3\ua8ne fibulae. The presence of these alloying elements thus gives an even more detailed technological and chronological picture of the metallurgical advances in the ancient region of Pannonia during the second and beginning of the first century BC. \uc2\ua9 2012 TMS
