No full textThe target of this work is to produce a vision of the geothermal potential stored in the depleted oil & gas fields in Italy, by using the available information provided by the Ministry of Economic Development, the published data on hydrocarbon fields, and the estimated temperature at depth from the Italian National Geothermal Database. Five most promising fields have been selected and the volume method has been applied to assess their geothermal potential. Then a probabilistic approach has been adopted to obtain not a single value but a distribution of values of the technical potential TP. The results indicate that the available heat in hydrocarbons fields is encouraging and it is fundamental to analyze the production capacities of the existing wells to have a clearer idea of the possible uses of this existing and wasted heat

No full textThe structural architecture of a portion of the eastern side of the Tyrrhenian Sea back-arc
basin has been defined reinterpreting a public dataset made up by seismic reflection profiles.
A detailed reconstruction of the extensional front migration trough time across the area has
been achieved.
Migration has been defined by identifying the generation of unconformities in the graben-like
basins developed in the area, as due to the activation and deactivation of normal faults. Such
phenomena are part of a tectonic process that also involved blocks rotation, crustal thinning
and stretching.
Syn-rift extension affected the area since the ?Early-Middle Miocene, principally interesting
the north-westernmost sectors. During late Miocene and throughout the Plio-Quaternary the
extensional front moved stepwise toward the southeastern and eastern sectors. Widespread
post-rift conditions established over the whole area since the late Pliocene-early Pleistocene.
Since the Quaternary the locus of active extension further migrated toward the present
onshore area, where a pronounced volcanic phase developed.
In this evolutionary framework the rates of observed migration could be correlated with the
acceleration of calabrian slab roll-back since Pliocene.
Furthermore direct evidences of magmatism were not recognized in the offshore. Although
the observed crustal thinning, the absence of volcanic bodies in the study area could be
related to normal faults which were unable to sufficiently extend the crust, in association with
lower crust and mantle processes unable to produce melts
