Journal ArticleDOI
How local stresses control magma-chamber ruptures, dyke injections, and eruptions in composite volcanoes
TL;DR: In this paper, a review of analytical and numerical models of local stresses around magma chambers, as well as analytical models and numerical examples of dyke-injection and eruption frequencies are presented.
Journal ArticleDOI
Infrastructure and mechanics of volcanic systems in Iceland
TL;DR: In this article, it is suggested that the local dyke swarms are supplied with magma largely from the deep-seated reservoirs, whereas the local sheet swarms were mainly fed from the associated crustal magma chambers.
Book
Rock Fractures in Geological Processes
TL;DR: In this article, the authors combine results from fracture mechanics, materials science, rock mechanics, structural geology, hydrogeology, and fluid mechanics to explore and explain fracture processes and fluid transport in the crust.
Journal ArticleDOI
Emplacement and arrest of sheets and dykes in central volcanoes
TL;DR: In this article, two principal mechanisms are proposed to explain the arrest of dykes and sheets in Iceland: local inclined (cone) sheets and regional dykes, and mechanical anisotropy whereby sheet intrusions become arrested at discontinuities.
Journal ArticleDOI
Magma chambers: Formation, local stresses, excess pressures, and compartments
TL;DR: In this paper, the in-situ tensile strength of a magma-chamber is estimated based on hydraulic fracture measurements in drill-holes worldwide down to crustal depths of about 9 km.
