Volcanism In The Campania Plain by

Original Title: Volcanism In The Campania Plain

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.

Plio Quaternary Volcanism In Italy by Angelo Peccerillo

Original Title: Plio Quaternary Volcanism In Italy

Central-Southern Italy and the Tyrrhenian Sea are the sites of extensive Plio-Quaternary magmatic activity. The rock compositions include crustal anatectic granites and rhyolites, tholeiitic, calc-alkaline, shoshonitic volcanics, and potassic to ultrapotassic and Na-alkaline volcanics. This very wide compositional variation makes Italian magmatism one of the most complex petrological issues, the understanding of which is a challenge for modern petrology and geochemistry. This book summarises the petrological, geochemical and volcanological characteristics of Italian Plio-Quaternary volcanism, and discusses petrogenetic hypotheses and possible geodynamics settings. The book is written for petrologists and geochemists, but fundamental geochemical information is well presented and the use of excessive jargon is avoided, making the book readable to a wide audience of Earth scientists.

Geohazard In Rocky Coastal Areas by Crescenzo Violante

Original Title: Geohazard In Rocky Coastal Areas

This Special Publication provides a range of methods and approaches for characterizing and modelling mass-wasting phenomena responsible for land degradation and erosion in rocky coastal areas. Rocky coasts occur in a variety of geological settings with a wide range of morphologies depending on rock type, tectonics and climate. In all these settings, slope instability represents the most important geological process that significantly influences the human use of coastal resources over a range of magnitudes and periods of recurrence.
