Transition from Vertical to Lateral Diking at the Neutral Buoyancy Line

Brice Tanguy Alphonse Lecampion, Andreas Möri, Dmitriy Garagash

Buoyant hydraulic fractures (HF) are a viable approach to model propagating magmatic intrusions in the lithosphere. Solutions for fully planar three-dimensional (3D) HF suggest the existence of a family of solutions as a function of fluid and solid propert ...

Magmatic Intrusions From a Hydraulic Fracture Modeling Perspective

Brice Tanguy Alphonse Lecampion, Andreas Möri

The emplacement of magmatic intrusions in the earth’s crust has been investigated for decades. The driving mechanism is the density difference between the fluid and the rock. In the absence of heterogeneities, this difference creates a constant buoyancy fo ...

Gravitational effects on theemergence,propagation,andarrestofhydraulicfractures

Brice Tanguy Alphonse Lecampion, Andreas Möri, Carlo Peruzzo, Dmitriy Garagash

Hydraulic fractures are driven by an internal fluid pressure exceeding the minimum compres- sive stress, propagating in a direction perpendicular to the latter. This class of tensile fractures has gained interest over the last fifty years due to the develo ...

Enrichment of immobile elements in synmagmatic fractures

Alexandra Roma Larisa Kushnir, Michael Heap

Useful minerals containing rare Earth elements (REE) and metals are sourced from magma bodies, but exactly how these elements initially leave the magma is not well known. Here we present textural and chemical analyses of mineral-filled fracture bands withi ...

Taking the pulse of volcanic eruptions using plagioclase glomerocrysts

Anders Meibom, Stéphane Laurent Escrig, Anders McCarthy, Pierre Vonlanthen

Crystallization timescales in subvolcanic systems and the consequences of interaction between ascending magmas and gases remain largely unconstrained, as do links between these processes and monitoring signals at restless volcanoes. We apply diffusion chro ...

PyFrac: A planar 3D hydraulic fracture simulator

Brice Tanguy Alphonse Lecampion, Haseeb Zia

Fluid driven fractures propagate in the upper earth crust either naturally or in response to engineeredfluid injections. The quantitative prediction of their evolution is critical in order to better understandtheir dynamics as well as to optimize their cre ...

Charge/discharge cycling of Li1+x(Ni0.6Co0.2Mn0.2)1−xO2 primary particles performed in a liquid microcell for transmission electron microscopy studies

Vasiliki Tileli, Tzu-Hsien Shen, Robin Pierre Alain Girod, Jing Hou

Ni-rich layered oxides are promising positive electrodes for fulfillment of government and industry targets for lithium-ion-battery-operated electric mobility purposes. Apart from ongoing research focusing on their design and material production, advanced ...

Plagioclase Glomerocrysts: taking the pulse of volcanic eruptions

Anders Meibom, Stéphane Laurent Escrig, Anders McCarthy

Volcanic eruptions result from complex interplay of magmatic processes including the ascent and storage of magma in the crust, volatile exsolution and crystallization. The dynamics of crystallization in shallow subvolcanic systems and the consequences of i ...

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 ...
