Fully-coupled 3D modelling of magmatic dike Propagation – finite pulse release from a point source

Brice Tanguy Alphonse Lecampion, Andreas Möri, Haseeb Zia

Magmatic dikes are a naturally occurring type of fluid-driven fractures [1] propagating in the lithosphere driven by buoyancy (more precisely by the difference between the in-situ minimum horizontal stress gradient and the magma weight). Fully-coupled mode ...

Bifurcations at the Stability Transition of Earthquake Faulting

Carolina Giorgetti

Tectonic faults typically break in a single rupture mode within the range of styles from slow slip to dynamic earthquake failure. However, in increasingly well-documented instances, the same fault segment fails in both slow and fast modes within a short pe ...

The influence of loading path on fault reactivation: a laboratory perspective

Marie Estelle Solange Violay, Carolina Giorgetti

Despite natural faults are variably oriented to the Earth's surface and to the local stress field, the mechanics of fault reactivation and slip under variable loading paths (sensu Sibson, 1993) is still poorly understood. Nonetheless, different loading pat ...

Energy budget of laboratory earthquakes: a comparison between linear elastic fracture mechanics approach and experimental approach

Marie Estelle Solange Violay, François Xavier Thibault Passelègue, Federica Paglialunga

Earthquakes correspond to a sudden release of elastic energy stored during inter-seismic period by tectonic loading around fault. The earthquake energy budget consists of four non-independent terms: the energy release rate (by unit crack length), the fract ...

An alternative model for the formation of hydrous Mg/Ni layer silicates ("deweylite"/"garnierite") in faulted peridotites of New Caledonia: II. Petrography and chemistry of white and green clay infillings

Gabrielle Dublet

This study, which complements a first mineralogical work, presents detailed petrographic and chemical data on the sequences of clay infillings commonly found in serpentine veins of reactivated faults from the New Caledonian peridotite formation. Chemical t ...

Emergence of self-affine surfaces during adhesive wear

Jean-François Molinari, Enrico Milanese, Ramin Aghababaei, Tobias Brink

Friction and wear depend critically on surface roughness and its evolution with time. An accurate control of roughness is essential to the performance and durability of virtually all engineering applications. At geological scales, roughness along tectonic ...

Origin of High-Frequency Radiation During Laboratory Earthquakes

François Xavier Thibault Passelègue

We monitor dynamic rupture propagation during laboratory stick-slip experiments performed on saw-cut Westerly granite under upper crustal conditions (10-90 MPa). Spectral analysis of high-frequency acoustic waveforms provided evidence that energy radiation ...

How does seismic anisotropy evolve as a function of mineralogical and textural changes across ductile shear zones? – an experimental and modelling approach

Henri Joseph François Gilles Leclère

Strain localization and the development of ductile shear zones in the middle and lower crust play major roles in lithosphere dynamics. Geophysical imaging of ductile shear zones is an issue for ore geology, for the understanding of the lithosphere rheology ...
