The book deals with the study of three important volcanisms in the
Campania Plain: Vesuvius, Campi Flegrei and Ignimbrites. The
knowledge of the volcanic evolution of Vesuvius and Campi Flegrei
has a particular relevance because of the hazards that these
volcanoes pose to the about 1.5 million people living in the
Neapolitan area.
The contributors to the volume bring new data (experiments on
volatile solubility, fluid-melt inclusions, tectonic, geophysical,
isotope, geochronology), which are helpful in the creation of new
models for a better understanding of the behaviour of the volcanic
systems. In particular a hydrothermal model is used to explain the
ground movements (bradyseism) at Campi Flegrei. To develop such a
model, the authors use an analogue for the evolving Campi Flegrei
sub-volcanic system, the model of the porphyry mineralized systems.
For Campanian Ignimbrite the authors highlight the impact
crystal-liquid separation has on melt compositional evolution and
particularly focus on trace element and Th isotope evidence for
open-system processes in the magma body associated with the
Campanian Ignimbrite.
The authors, for their interpretations, utilize thermodynamic and
quantitative mass balance modelling of major and trace element data
and semi-quantitative limits on Th and Sr isotopes to evaluate the
role of crytal-melt separation, magma-fluid interaction, and
assimilation of wallrock on the geochemical evolution of the
Campamian Ignimbrite.
