Stratigraphy of pliocenic-pleistocenic (subordinately
permian) volcanic successions of mediterranean (Aeolian
archipelago, Palmarola, Pantelleria ecc.) and extra-mediterranean
areas (Tatio area, Chile):
1. geological survey in volcanic areas aimed at defining major
stratigraphic relationships by means of a stratigraphic approach
based on the prioritary use of Unconformity-Bounded Units
(UBU);
2. stratigraphic and sedimentological analysis towards the
characterization of eruptive style and depositional behaviour of
pyroclastic deposits in subaerial and submarine environments;
3. interaction between volcanism, late Pleistocene sea level
changes and vertical crustal movements in volcanic areas (Aeolian
Islands).
4. erosional processes and flank instability during the
geological evolution of volcanic islands.
5. evaluation of hazard and volcanic risk.
The geological survey is aimed to reconstruct a stratigraphic
framework of the studied areas with the purpose to highlight its
geological evolution. At this purpose, particular attention will be
devoted to the recognition of main unconformities useful to provide
an interpretative model of the evolution of volcanic edifices as
the result of "constructive" phases, testified by the occurring of
volcanic products, and the phases of reworking in subaerial
environment. The reconstructed stratigraphy would represent an
essential tool of synthesis at wide scale and would provide a
fundamental framework where geochemical and petrological data could
be included from the sake to match and integrate the stratigraphic
results.
