La caliza de Espejón (Soria, España): caracterización arqueométrica

This paper presents the first results of the archaeometric characterization of four lithological varieties of Espejon limestone, outcropping on the province of Soria and used in Roman times. Petrographic analysis (optical transmitted light microscopy –OM-), cathodoluminescence (CL), spectrometry energy dispersive X-ray (EDX) and mass spectrometry of stable isotope ratios of carbon and oxygen (δ13C y δ18O) (IRMS) have been carried out on samples collected from quarries. The results form the basis of the reference core of these limestones, which will be subsequently used for future comparisons with archaeological items in order to determine the use and distribution of these limestones in Roman Hispania.
