Palaeomagnetism and K-Ar Ages of Neogene Rocks of Northern Taiwan: Tectonics of the Arc Junction of Ryukyu and Luzon Arcs [PDF]
SUMMARY More than 100 block samples were collected for palaeomagnetic and geochronological studies from 14 sites in Miocene and Plio-Pleistocene volcanic rocks in the western foothills province of northern Taiwan, in an attempt to understand the tectonic evolution of the junction of the Ryukyu and the Luzon arcs.

Abstract Intermediate‐depth intraslab earthquakes in the Philippine Sea Plate occur at depths of 100–200 km beneath the Ryukyu Arc and are widely interpreted as manifestations of slab dehydration; however, the spatial variability in continuity of the volcanic front and the asymmetric distribution of volcanic activity are poorly explained by existing ...

Link between Crustal Magnetization and Earthquakes in Taiwan
The active Taiwan orogen is located between the Ryukyu subduction zone in the northeast and the Manila subduction zone in the south. Intensive collision from the northwestward motion of the Luzon Arc has induced enormous earthquakes in and around Taiwan.

Slab horizontal subduction and slab tearing beneath East Asia [PDF]
The present‐day architecture of subducted slabs in the mantle as inferred from seismic tomography is a record of plate tectonics through geological time. The unusually large slab that lies nearly horizontally above the 660‐km mantle discontinuity beneath

Segmentation of the Izu-Bonin and Mariana slabs based on the analysis of the Benioff seismicity distribution and regional tomography results [PDF]
We present a new model of P and S velocity anomalies in the mantle down to a depth of 1300 km beneath the Izu-Bonin and Mariana (IBM) arcs. This model is derived based on tomographic inversion of global travel time data from the revised ISC catalogue ...

Flux and Isotopic Composition of Sedimentary Carbon Subducting Along the World's Trenches
Abstract Here we provide comprehensive estimates for the subducted sedimentary flux of inorganic and organic carbon and δ13C at 16 trench segments worldwide. Our calculations provide minimum (incoming sediment), maximum (trench fill) and best estimates (underthrust) of carbon fluxes.

Moho Fold Structure Beneath the East China Sea and Its Tectonic Implications
Moho fold structures provide critical insights into the tectonic evolution of the East China Sea. However, previous models exhibit substantial uncertainties, primarily resulting from the unaccounted gravitational effects of crustal sources and ...

Active normal faults and submarine landslides in the Keelung Shelf off NE Taiwan
The westernmost Okinawa Trough back-arc basin is located to the north of the Ryukyu islands and is situated above the northward dipping Ryukyu subducted slab.

Seismic Lg-wave attenuation tomography: Method, algorithm, data processing flow and application
With the rapid development of modern seismic network, seismological signals can be digitally recorded in broad frequency band, larger dynamic range, and higher spatial density, which provide the possibility of obtaining fine structures of the quality ...
