Estudio arqueométrico de tres piezas pétreas de Campo Real/Fillera (Sos del Rey Católico-Sangüesa)

Abstract

Recently, three pieces of stone nature from the Roman site of Campo Real/Fillera (Sos del Rey Católico-Sangüesa) have been located. The pieces correspond to one fragment of paving stone and two incomplete column shafts. In this paper, we show the analytical data obtained from the archaeometric study of these pieces. The analysis has led to the lithological characterization of rock samples in order to investigate the provenance of marble used. Methodologically we have made a petrographic study under thin section and a stable isotope analysis of 13C and 18O. The determination of the quarry provenance is made by comparison, using the same methodology applied to a wide collection of marbles from peninsular and Mediterranean quarries exploited in Antiquity.
