Modeling Geoid and Dynamic Topography From Tomography‐Based Thermo‐Chemical Mantle Convection
Abstract Mantle convection causes the most important contribution to the geoid and dynamic topography. With mantle density inferred from high‐resolution tomography models and numerical methods solving the governing equations of viscous mantle flow, the modeled geoid can fit the observations well.

Abstract We present new vector paleomagnetic data from 13 radiometrically dated lava‐flows in southern La Palma (Canary Islands) spanning from 1 to 56 ka, which covers most of the Late Pleistocene to prehistoric Holocene volcanic record in the island.

Strength α‐Quartz: New Results From High Pressure In Situ X‐Ray Diffraction Experiments
Abstract We present a suite of 13 uniaxial deformation experiments on fine grained polycrystalline α‐quartz conducted in a D‐DIA apparatus monitored with in situ synchrotron x‐rays. Experimental temperatures range from 25°C to 1199°C with pressures between 1.4 and 3.2 GPa, and strain rates between 3.4 × 10−6 s−1 and 1.8 × 10−5 s−1.

Abstract The study of silicate glasses is important to understand the physical and chemical properties of silicate melts under high‐pressure conditions relevant to planetary interiors. We conducted in situ Brillouin spectroscopy measurements on two endmember, low‐impurity CaSiO3 glasses and one Fe, Al, Mg, Ti‐bearing CaSiO3 glass up to 23 GPa.

Abstract Fluids released from subducting hydrated rocks influence volcanism, tectonics, and geochemical cycling, but the mechanisms of fluid escape in subduction zones remain poorly understood. We address this issue by investigating the Erro‐Tobbio meta‐serpentinites (ET‐MS), Italy, exhumed serpentinite rocks that preserve extensive dehydration vein ...
