Role of mechanical erosion in controlling the effusion rate of basaltic eruptions

open access: yesGeophysical Research Letters, 2016
In many basaltic eruptions, observations show that the effusion rate of magma has a typical dependence on time: the effusion rate curves show first a period of increasing and later a decreasing phase by a maximum value. We present a model to explain this

Temperatures of entering magma, formation and dimensions of magma chambers of volcanoes

open access: yesBulletin Volcanologique, 1982
A mechanism, of formation of magma chambers that feed volcanoes is discussed. Heat conditions and dimensions of magma chambers which have existed for more than several thousand years may become stable. The approximate equations of heat balance of these chambers are derived by calculating the temperatureT1 of the magma entering chambers and the radiia ...

The shallow magma chamber of Stromboli Volcano (Italy)

open access: yesGeophysical Research Letters, 2017
In this work, we integrate artificial and natural seismic sources data to obtain high‐resolution images of the shallow inner structure of Stromboli Volcano. Overall, we used a total of 21,953 P readings from an active seismic experiment and an additional

Igneous Layering in Basaltic Magma Chambers

open access: yes, 2015
Layering is a common feature in mafic and ultramafic layered intrusions and generally consists of a succession of layers characterized by contrasted mineral modes and/or mineral textures, including grain size and orientation and, locally, changing mineral compositions.

Explosive volcanism, shock metamorphism and the K-T boundary [PDF]

open access: yes
The issue of whether shocked quartz can be produced by explosive volcanic events is important in understanding the origin of the K-T boundary constituents.
