We have determined a detailed three-dimensional P wave velocity structure of the Japan subduction zone to 500-km depth by inverting local, regional, and teleseismic data simultaneously. We used 45,318 P wave arrivals from 1241 shallow and deep earthquakes which occurred in and around the Japan ...
The Neoproterozoic amphibolites and related rocks along the Ailaoshan zone may be the southward extension of the Neoproterozoic supra-subduction zone that developed along the western margin of the Yangtze Block. 展开 关键词: Ailaoshan zone Amphibolite Zircon U-Pb dating Petrogenesis Neoproterozoic ...
The Cycle of Hydration and Fluid Release in the Costa Rican Subduction Zone imaged through electromagnetic soundings: Where has all the water gone? (Invited talk) Here we present an image of the hydration and dehydration cycle down to 120 km depth in one setting derived by an onshore-offshore...
Seismic attenuation structure in central Mexico: Image of a focused high-attenuation zone in the mantle wedge [1]聽Velocity spectra from moderate-sized earthquakes were used to investigate the P wave attenuation structure in central Mexico. In particular, we includ... Ting,Chen,Robert,... - 《...
Transects of the submersible Alvin across rock outcrops in the Oregon subduction zone have furnished information on the structural and stratigraphic framework of this accretionary complex. Communities of clams and tube worms, and authigenic carbonate mineral precipitates, are associated with venting sites...
Upper mantle structure of the northern Cascadia subduction zone Previous knowledge of the structure of the Cascadia subduction zone north of the Canada–United States border has been derived from a variety of geophysica... M.,G.,Bostock,... - 《Canadian Journal of Earth Sciences》 被引量: 94...
Tectonic sediment thickening, fluid expulsion, and the resulting thermal regime of the northern Cascadia subduction zone accretionary prism have been described by numerical models. Both the sediment thickening and the fluid expulsion are found to have important thermal effects. Constraints on the models ...

However, the Hf isotopic budget of the oldest sediments is more influenced by continental material than the younger sediments, despite the large distances to continental masses 130 Ma ago. In the Izu subduction zone, we calculate a sedimentary input of less than about 2% in the volcanic lava ...
The apparent success of the dislocation model in forward and inverse modeling of subduction zone interseismic deformation is largely due to the use of an Effective Transition Zone (ETZ) between the updip locked zone and the zone of full slip at depths. The ETZ of a subduction interface is phi...
