Abstract(s)
Mapping of clay resources in the Cenozoic deposits of the Tábua region (central Portugal) has been carried out, together with the chemical, mineralogical and
technological characterization of seventeen clay samples. The study was undertaken to relate the lithostratigraphic units and the typology of raw materials
with regard to the manufacture of ceramics. The sedimentary succession comprises two units with different suitability for the manufacture of ceramics: an
upper unit, with clays that present technological restrictions; and a lower unit with a much greater potential. A small set of parameters has been identified
which differentiate the typological units. These parameters allow a realistic estimation to be made of the ceramic properties of any clay layer sampled in the
study area. It is anticipated that with minor field work and sampling, the typological column can also be used in adjacent areas.
