| Abstract: | Results of a research carried out on the lavas from Campi Flegrei and Somma-Vesuvius volcanic districts are reported here.
The lavas have been widely employed, since Roman age, in several important monumental buildings of the Campania region, mainly
in the town of Naples and in its province. They are classified as trachytes (Campi Flegrei products), tephri-phonolites and
phono-tephrites (Somma-Vesuvius complex) from a petrographical point of view. Sampling was carried out from well-known exploitation
districts. A substantial chemical difference between the products of the two sectors was confirmed, while petrophysical characterization
evidenced similarity among the two different materials, although some differences were recorded even in samples coming from
the same exploitation site. |
