Abstract
AbstractSamples of two lenticular clay bodies from a Cretaceous deposit near Padrão (Lousã basin) were characterized by INAA, XRD and Mössbauer spectroscopy. This clay is believed to be the raw material used to manufacture the Iron Age and Roman fine grey pottery from Conímbriga. The differences observed in the chemical and mineralogical compositions of the clay samples and of different size fractions are consistent with the high variance found in the compositional group corresponding to that archaeological site.
