Influence of host magma alkalinity on trachytic melts formed during incongruent orthopyroxene dissolution in mantle xenoliths


We have studied reaction textures developed in peridotite xenoliths hosted in alkali basalts to understand why and how siliceous glasses developed with respect to their host rocks, determining the formation of minerals and their subsequent re-equilibration in the reaction zone, and the timescales of their formation.

Volcanism in the Chugoku region: a review for the first UNESCO field school on Geoenvironmental disaster reduction

Mount Daisen

This review will provide a brief overview of the geology of southwest Japan with special emphasis on the igneous and volcanic evolution. It will give participants of the UNESCO field school a minimum of required background into one of the most diverse and interesting volcanic field areas in the world.

The 2010 - 2013 Eruption of Kizimen Volcano

Kizimen Volcano

Between 2010 and 2013, after a dormancy of more than 80 years, Kizimen volcano, Kamchatka entered a new cycle of activity. Eruptions during this episode produced several pyroclastic flows as well as lava flows. A detailed investigation of this eruption showed, how strong, persistent fumarolic activity can notably affect the behaviour of forthcoming eruptions.
