Structures et Propriétés physiques des magmas

Analogue experiments on compaction and shearing of wet granular media : Implications for rheology and structures in crystallizing magmas

In a cooling magma, rheological changes are primary controlled by the progressively increasing crystallinity and related melt fraction threshold(s) marking changes in deformation mechanisms. We (...)

Flow mechanism in partially molten gabbro

Although they show no or little crystal-plastic deformation, the Oman ophiolite gabbros are affected by numerous deformation structures, including foliations, lineations, folds and shear bands. (...)

Modelling the seismic properties of partially crystallized gabbro

A model of seismic velocities in partially cristallized gabbros shows that, taking into account the anisotropy of basaltic melt distribution in the crystalline aggregate (deduced from textural (...)

Experimental study of low-frequency attenuation in partially molten gabbro

This study aimed to better characterize seismic properties of a partially cristallized/molten gabbro, by measuring attenuation in Oman gabbronorite samples at low frequencies. Experiments were (...)
