Analysis of a Permo-Triassic polarity transition in different absolute reconstructions of Pangaea,considering a model with features of the present Earth magnetic field
Permo-Triassic Pangaea absolute reconstruction Earth magnetic field polarity transition
2015/9/2
The main objective of this paper is to show that the distribution of transitional palaeomagnetic data recorded at 250 Ma are in agreement with simulated data that depend on the sampling site, using a ...
Simulation of seismic waves at the earth's crust (brittle–ductile transition) based on the Burgers model
In the crust regional toughness seismic waves the stress-strain relationship seismic attenuation
2015/1/6
The earth's crust presents two dissimilar rheological behaviors depending on the in situ stress-temperature conditions. The upper, cooler part is brittle, while deeper zones are ductile. Seismic waves...
Mantle lithosphere transition from the East European Craton to the Variscan Bohemian Massif imaged by shear-wave splitting
Seismic shear wave splitting focused on the structure of the upper mantle
2015/1/6
We analyse splitting of teleseismic shear waves recorded during the PASSEQ passive experiment (2006–2008) focused on the upper mantle structure across and around the Trans-European Suture Zone (TESZ)....
Influence of the Ringwoodite-Perovskite transition on mantle convection in spherical geometry as a function of Clapeyron slope and Rayleigh number
Ringwoodite-Perovskite transition mantle convection spherical geometry Clapeyron slope Rayleigh number
2014/12/31
We investigate the influence on mantle convection of the negative Clapeyron slope ringwoodite to perovskite and ferro-periclase mantle phase transition, which is correlated with the seismic discontinu...
Incipient sediment motion across the river to debris-fl ow transition
Incipient sediment motion the river debris-fl ow transition
2014/4/8
Sediment transport in mountain channels controls the evolution of mountainous terrain in response to climate and tectonics and presents major hazards to life and infrastructure worldwide. Despite its ...
Interaction of Cocos and Rivera plates with the upper-mantle transition zone underneath central Mexico
Mantle processes Phase transitions North America
2014/4/10
Receiver functions (RFs) from 224 permanent and temporary stations in central and southern Mexico were used to characterize the upper-mantle transition zone in that region. Discontinuities at 410 and ...
Low-order models of wave interactions in the transition to baroclinic chaos
Low-order models wave interactions baroclinic chaos
2009/11/16
A hierarchy of low-order models, based on the quasi-geostrophic two-layer model, is used to investigate complex multi-mode flows. The different models were used to study distinct types of nonlinear in...
Supershear transition due to a free surface in 3-D simulations of spontaneous dynamic rupture on vertical strike-slip faults
Supershear transition Earthquake rupture dynamics Earthquake source physics
2014/4/8
Supershear rupture propagation has been inferred from seismic observations for natural faults and observed in laboratory experiments. We study the effect of the free surface on the transition of earth...
Resonant-to-nonresonant transition in electrostatic ion-cyclotron wave phase velocity
Resonant-to-nonresonant transition electrostatic ion-cyclotron wave phase velocity
2009/11/11
Because of the implications for plasmas in the laboratory and in space, attention has been drawn to inhomogeneous energy-density driven (IEDD) waves that are sustained by velocity-shear-induced inhomo...
Transition of mode II cracks from sub-Rayleigh to intersonic speeds in the presence of favorable heterogeneity
Dynamic fracture Supershear transition of earthquakes Crack mechanics Elastic material Boundary integral equations
2014/4/8
Understanding sub-Rayleigh-to-intersonic transition of mode II cracks is a fundamental problem in fracture mechanics with important practical implications for earthquake dynamics and seismic radiation...
Crustal structure of the Borderland-Continent Transition Zone of southern California adjacent to Los Angeles
California Borderland LARSE transition zone slab
2014/4/10
We use data from the onshore-offshore component of Los Angeles Region Seismic Experiment (LARSE) to model the broad-scale features of the midcrust to upper mantle beneath a north-south transect that s...
