On the effects of fluid pressure variations on rock-mass and fault mechanical behaviour

In the past 20 years, the growing interest in deep geo-reservoirs for purposes such as carbon storage, waste water disposal, or geothermal energy exploitation have led to large-volume fluid injections into the upper continental crust. These fluid injection ...

Geometrical control of fluid flow through single carbonate fracture

Fluid flow through single rough surface is critical for many geophysical processes and engineering applications. Thus, relations between flow and surrounding fracture geometry will be investigated. Four pairs of engineered Carrara marble surfaces with diff ...

On the scaling between precursory moment release and earthquake magnitude: Insights from the laboratory

Marie Estelle Solange Violay, François Xavier Thibault Passelègue, Mateo Alejandro Acosta

Recent seismological observations highlighted that both aseismic silent slip and/or foreshock sequences can precede large earthquake ruptures (Tohoku-Oki, 2011, Mw 9.0 (Kato et al., 2012); Iquique, 2014, Mw 8.1 (Ruiz et al, 2014; Socquet et al., 2017); Ill ...

Fluid thermodynamics control fault heating and weakening under upper crustal stress conditions

Marie Estelle Solange Violay, François Xavier Thibault Passelègue, Mateo Alejandro Acosta

Although fluids are pervasive among tectonic faults, thermo-hydro-mechanical couplings during earthquake slip remain unclear. In particular, fluid induced seismicity is today a subject of major interest for the geo-energy community. We report full dynamic ...

Porosity evolution at the brittle-ductile transition in the continental crust: Implications for deep hydro-geothermal circulation

Marie Estelle Solange Violay, Mateo Alejandro Acosta, Michael Heap

Recently, projects have been proposed to engineer deep geothermal reservoirs in the ductile crust. To examine their feasibility, we performed high-temperature (up to 1000 degrees C), high-pressure (130 MPa) triaxial experiments on granite (initially-intact ...

Collision-Free Coordination of Fiber Positioners in Multi-object Spectrographs

Denis Gillet, Jean-Paul Richard Kneib, Laleh Makarem

Many ber-fed spectroscopic survey projects, such as DESI, PFS and MOONS, will use thousands of fiber positioners packed at a focal plane. To maximize observation time, the positioners need to move simultaneously and reach their targets swiftly. We have pre ...

Mechanical and microstructural characteristics of Ti6Al4V/AA2519 and Ti6Al4V/AA1050/AA2519 laminates manufactured by explosive welding

Marco Cantoni

The aim of the work was to produce laminated structures consisting of Ti-6Al-4V alloy and AA2519 plates and to investigate their microstructure and mechanical properties with anemphasis on the role of an additional AA1050 interlayer. Explosive welding was ...

Multilevel and Local Timestepping Discontinuous Galerkin Methods for Magma Dynamics

Jan Sickmann Hesthaven

Discontinuous Galerkin (DG) method is presented for numerical modeling of melt migration in a chemically reactive and viscously deforming upwelling mantle column. DG methods for both advection and elliptic equations provide a robust and efficient solution ...

The structure and effect of suture zones in the Larsen C Ice Shelf, Antarctica

Konrad Steffen

Ice shelf fractures frequently terminate where they encounter suture zones, regions of material heterogeneity that form between meteoric inflows in ice shelves. This heterogeneity can consist of marine ice, meteoric ice with modified rheological properties ...

Petrophysical properties of the root zone of sheeted dikes in the ocean crust: A case study from Hole ODP/IODP 1256D, Eastern Equatorial Pacific

Marie Estelle Solange Violay

ODP (Ocean Drilling Program)/IODP (Integrated Ocean Drilling Program) Site 1256 is located on the Cocos Plate in the Eastern Equatorial Pacific Ocean, in a 15. Ma old oceanic lithosphere formed at the EPR during a period of superfast spreading (> 200 mm/yr ...
