Persistent degassing of closed-conduit explosive volcanoes may be used to inspect and
monitor magmatic processes. After interaction with shallow hydrothermal fluids, volcanic …

New geochemical and isotopic data on volcanic rocks spanning the period~ 75–50 ka BP on
Ischia volcano, Italy, shed light on the evolution of the magmatic system before and after the …

Defining the magma storage conditions of a volcanic system is a major goal in modern
volcanology due to its direct implications for the style of a possible eruption and thus on the …

Petrological data have been acquired on natural trachytes from the Chaîne des Puys,
French Massif Central, and on experimental products from phase equilibria to (1) constrain …

Barium diffusion chronometry applied to sanidine phenocrysts from the trachytic Agnano-
Monte Spina eruption (∼ 4.7 ka) constrains the time between reactivation and eruption of …

Selected phlogopite flakes from Mt. Vulture in southern Italy were studied using a
combination of single-crystal techniques: electron microprobe analysis (EMPA), secondary …

The crystal chemistry of Ti-rich phlogopite from deposits of the oldest activity (~ 740 ka) of Mt.
Vulture, Potenza, Italy, was investigated to identify the substitution mechanisms in Ti-rich …

The petrochemical characteristics of the Campi Flegrei juvenile products are here reviewed
in order to give a comprehensive portrait of the main processes governing magma evolution …

Abstract The Glass Mountain obsidians (Long Valley, CA) are crystal poor (< 8 vol%) and
highly evolved (high SiO 2, low Sr), and therefore, their formation required extremely efficient …

This study reports the first crystal chemical database resulting from a detailed structural
investigation of trioctahedral micas found in xenolithic ejecta produced during the AD 1631 …
