Abstract
Bathymetric and gravity surveys were carried out from 1988 to 1994, in the Gulf of Naples (Southern Italy) to
offshore extend the already existing Bouguer anomaly map. In order to improve the knowledge of the
structural setting beneath the active Neapolitan volcanoes (Vesuvio, Campi Flegrei and Ischia), 862 stations
were surveyed within the isobath of 400 m; at the same time, and about 2000 on-land gravity values were
also collected. A new Bouguer anomaly map spanning the whole volcanic region was drawn from the final
data set. Gravity anomalies were referred to the new absolute gravity station in Naples and computed
according to 1980 Geodetic Reference System. Finally, a density value of 2200 kg/m3 was used in the
computation of the Bouguer and terrain effects. We carried out the inversion of the gravity anomalies
adopting a 2.5-D modelling along selected profiles crossing the investigated area. The interpretative models
were constrained to data obtained from deep wells and other geophysical investigations.
In a previous paper, we investigated in detail the area around the Vesuvio. Here we focus on the Phlegraean
Volcanic District (PVD), formed by Campi Flegrei, and the islands of Procida and Ischia. Our interpretation
permits to outline two separate caldera-like structures in Campi Flegrei and their rims, mainly in the offshore
sector. Moreover, it highlights a sharp separation between the island of Ischia and the rest of the PVD while
showing Procida as well integrated, at least from the structural point of view. Ischia appears to be a block
delimited all around and stepped by a series of volcano–tectonic structures. Both the qualitative description
and the quantitative interpretation of the Bouguer anomaly in the PVD area, together with the comparison
with the gravity features of the rest of the Neapolitan area, would suggest that the uprising basement
beneath the island of Ischia, inducing most of the gravity signal, could be the carbonate ones. The certainty
and the discrimination between a carbonate or lava basement beneath Campi Flegrei is not yet deducible. In
addition, for this area, the presence of a magma chamber from the Bouguer anomaly, taking into account the
information provided by further geophysical and geochemical researches, was checked. The add-on body
improves the model as a whole and doesn't impact on the presence of a residual magma chamber.
Finally, the quantitative interpretation also permitted to define the shape and the depth of the 2600 kg/m3
basement (carbonate in places) and of the overlapping denser polygenic layer on which the inferred main
structures was drawn.
