Scanning ion microscopy (SIM) and secondary ion mass spectrometry (SIMS) have been used to study an Early Iron Age bronze bracelet (armilla) found in the Necropolis of Chiavari (Genoa), Ion induced secondary electron images of the longitudinally sectioned armilla have been compared with the secondary ion images obtained over the same area. A pronounced segregation of chlorine and sulphur has been observed at the corroded grain boundaries while inclusions of iron and lead, overlapped with sulphur and chlorine, respectively, has been observed inside the grains.

Abstract
Scanning ion microscopy (SIM) and secondary ion mass spectrometry (SIMS) have been used to study an Early Iron Age bronze bracelet (armilla) found in the Necropolis of Chiavari (Genoa), Ion induced secondary electron images of the longitudinally sectioned armilla have been compared with the secondary ion images obtained over the same area. A pronounced segregation of chlorine and sulphur has been observed at the corroded grain boundaries while inclusions of iron and lead, overlapped with sulphur and chlorine, respectively, has been observed inside the grains.File in questo prodotto:
