At plate boundaries, where deformation is localized along centimetre-to kilometre-scale
shear zones, the influence of serpentinite on tectonic processes is linked to its unique …

Hydrogen and deuterium isotopic evidence indicates that the source of terrestrial water was
mostly meteorites, with additional influx from nebula gas during accretion. There are two …

In this section the contribution of CPO to seismic anisotropy in the deep Earth with cases of
olivine and the role of melt is illustrated. The CPO in rocks of upper-mantle origin is now well …

Abstract The European Alps are the site where classic geologic concepts such as nappe
theory, continental subduction and slab breakoff have been first proposed. However, the …

Here we provide an appraisal of the Poisson's ratios (υ) for natural elements, common
oxides, silicate minerals, and rocks with the purpose of searching for naturally auxetic …

Brillouin spectroscopy is an optical technique that allows one to determine the directional
dependence of acoustic velocities in minerals and materials subject to a wide range of …

The evolution of the ratio between P-and S-wave velocities (VP/VS) with increasing fluid-
saturated porosity is computed for isotropic rocks containing spheroidal pores. The ratio …

The dynamics of continental subduction is largely controlled by the rheological properties of
rocks involved along the subduction channel. Serpentinites have low viscosity at geological …

Using first principle simulations we calculated the elasticity of chlorite. At a density ρ~ 2.60 g
cm− 3, the elastic constant tensor reveals significant elastic anisotropy: VP~ 27%, VS1 …

Abstract The 3.65 Å phase [MgSi (OH) 6] is a hydrous phase that is predicted to be stable in
a simplified MgO-SiO2-H2O (MSH) ternary system at pressures exceeding 9 GPa. Along …
