oint Inversion of the 3D P Wave Velocity Structure of the Crust and Upper Mantle under the Southeastern Margin of the Tibetan Plateau Using Regional Earthquake and Teleseismic Data
3D P-wave velocity structure China seismic array detection Panxi region Chuan-Dian Block Daliangshan Block southeastern margin of Qinghai–Tibet Plateau
2018/4/10
The special seismic tectonic environment and frequent seismicity in the southeastern margin of the Qinghai–Tibet Plateau show that this area is an ideal location to study the present tectonic movement...
CT scan of Earth links deep mantle plumes with volcanic hotspots（图）
CT scan Earth links deep mantle plumes volcanic hotspots
2015/9/8
or the first time a sharp, three-dimensional scan of Earth’s interior that conclusively connects plumes of hot rock rising through the mantle with surface hotspots that generate volcanic island chains...
Seismic structure of the lithosphere and upper mantle beneath the ocean islands near mid-oceanic ridges
Seismic structure the lithosphere and upper mantle beneath ocean islands near mid-oceanic ridges
2015/1/6
Deciphering the seismic character of the young lithosphere near mid-oceanic ridges (MORs) is a challenging endeavor. In this study, we determine the seismic structure of the oceanic plate near the MOR...
Domains of Archean mantle lithosphere deciphered by seismic anisotropy – inferences from the LAPNET array in northern Fennoscandia
Archean mantle lithosphere deciphered seismic anisotropy the LAPNET array northern Fennoscandia

An international LAPNET array (2007–2009, http://www.oulu.fi/sgo-oty/lapnet) of the POLENET/LAPNET sub-project of the POLENET-IPY consortium, related to seismic and geodetic studies in the Arctic regi...
Generation of talc in the mantle wedge and its role in subduction dynamics in central Mexico
Subduction talc serpentine receiver function mantle wedge P-to-S velocity ratio
2014/4/10
Geophysical evidence shows the presence of low-seismic velocity material at the surface of slabs in subduction zones. In the central Mexican subduction zone this appears as a thin (～4 km) low-velocity...
Evidence of upper-mantle processes related to continental rifting versus oceanic crust in the Gulf of California
Mantle processes Phase transitions North America
2014/4/10
Receiver functions from teleseismic events, recorded by stations around the Gulf of California, are used to map the upper-mantle seismic discontinuities. We observe a mean transition zone thickness co...
Rolling hills on the core–mantle boundary
core–mantle boundary (CMB) iron-rich (Mg,Fe)O USArray low velocity zone
2014/4/10
Recent results suggest that an iron-rich oxide may have fractionally crystallized from a primordial magma ocean and settled on the core–mantle boundary (CMB). Based on experimental results, the presen...
The Relationship Between Upper Mantle Anisotropic Structures Beneath California, Transpression, and Absolute Plate Motions
The Relationship Between Upper Mantle Anisotropic Structures California Transpression Absolute Plate Motions
2014/4/10
We calculated SKS splitting parameters for the California Integrated Seismic Network. In southern California, we also estimated splitting in the upper 100 km using azimuthal anisotropy determined fr...

Seismic attenuation structure in central Mexico: Image of a focused high-attenuation zone in the mantle wedge
Seismic attenuation structure central Mexico Image of a focused high-attenuation zone the mantle wedge
2014/4/10
Velocity spectra from moderate-sized earthquakes were used to investigate the P wave attenuation structure in central Mexico. In particular, we included regional events with magnitudes in the range of...
The Sumatra subduction zone: A case for a locked fault zone extending into the mantle

2014/4/15
A current view is that the portion of the subduction interface that remains locked in the time interval between large interplate earthquakes, hereinafter referred to as the locked fault zone (LFZ), do...
Mantle Heterogeneities and theSCECReference Three-Dimensional Seismic Velocity Model Version 3
Mantle Heterogeneities Three-Dimensional Seismic Velocity Model
2014/4/10
We determine upper mantle seismic velocity heterogeneities below Southern California from the inversion of teleseismic travel-time residuals. TeleseismicP-wave arrival times are obtained from three te...
