International Journal of Geophysics, 2011 Broadband seismic deployments have been carried out in the Lützow-Holm Bay region (LHB), Dronning Maud Land, East Antarctica. The recorded teleseismic and local events are of sufficient quality to image the structure and dynamics of the crust and mantle

Nature Communications, 2020 Knowledge of shear-wave anisotropy is important to understanding the structure and dynamics of the subduction zone mantle wedge. Here, the authors find unambiguous evidence that forearc anisotropy resides in the upper-plate crust, while weak anisotropy ...

, 2012 We combine density functional theory (DFT) within the local density approximation (LDA), the quasiharmonic approximation (QHA), and a model vibrational density of states (VDoS) to calculate elastic moduli and sound velocities of gamma-[Fe_x,Mg_(1-x ...

Non-Linear Effects of Gravity Change on Mantle Dynamics
GeosciencesStarting from observed variations of the length of day in the past 2.5 billion years, we calculate the corresponding gravity variation and evaluate the possible effects that such variation would have induced on the lithosphere and on mantle convection ...

Fluid Dynamics of Mantle Plumes
, 2007 A ‘hotspot’ (Wilson 1963) is a long-term source of volcanism which is fixed relative to the plate overriding it. Common signatures of hotspots include a bathymetric swell and an associated gravity anomaly; basalt geochemistry different from normal mid-ocean ridge basalts; and volcanic chains with a clear age progression parallel to the plate motion, in

Report of the panel on earth structure and dynamics, section 6 [PDF]
The panel identified problems related to the dynamics of the core and mantle that should be addressed by NASA programs. They include investigating the geodynamo based on observations of the Earth's magnetic field, determining the rheology of the mantle ...

Robust β‐myrcene block copolymer elastomeric vitrimers
Polymer International, EarlyView.Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

, 2007 [1] In the Apennines subduction (Italy), earthquakes mainly occur within the overriding plate, along the chain axis. The events concentrate in the upper 15 km of the crust above the mantle wedge, and focal solutions indicate normal faulting. In the foreland, the seismogenic volume affects the upper 35 km of the crust.

Vesicularity, bubble formation and noble gas fractionation during MORB degassing
, 2013 The objective of this study is to use molecular dynamics simulation (MD) to evaluate the vesicularity and noble gas fractionation, and to shed light on bubble formation during MORB degassing.
