Sedimentological characteristics of ice-wedge polygon terrain in Adventdalen (Svalbard) – environmental and climatic implications for the late Holocene
Ice wedge periglacial landscape svalbard river terraces radioactive carbon s
2015/1/6
Ice wedges are widespread periglacial features in the landscape of Adventdalen, Svalbard. The networks of ice wedges have created areas with well-developed polygonal terrains in the lowest fluvial ter...
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...
Low friction along the high slip patch of the 2011 Mw 9.0 Tohoku-Oki earthquake required from the wedge structure and extensional splay faults
Low friction along the high slip patch 2011 Mw 9.0 Tohoku-Oki earthquake required the wedge structure extensional splay faults
2014/4/15
We analyze the mechanical properties needed to account for the large shallow slip during the 2011 Tohoku-Oki earthquake and the activation of landward normal faulting within the forearc. We show that ...
Numerical simulations of an ocean/continent convergent system: influence of subduction geometry and mantle wedge hydration on crustal recycling
ocean/continent convergent system Numerical simulations subduction geometry and mantle wedge hydration
2011/9/5
The eects of the hydration mechanism on continental crust recycling are analyzed through a 2D nite element thermo-mechanical model. Oceanic slab dehydration and consequent mantle wedge hydration are...
The Neogene Xiyu Formation, a diachronous prograding gravel wedge at front of the Tianshan: Climatic and tectonic implications
Xiyu Formation magnetostratigraphy Tianshan gravel wedge progradation shortening rates
2014/4/15
The Tarim and Junggar basins in central Asia are capped by a thick pile of conglomerates, called the Xiyu Formation, that are commonly linked to a change in climate and/or accelerated uplift near the ...
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...
