Volcanic Characteristics of Kueishantao in Northeast Taiwan and Their Implications

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2010
Kueishantao (KST) is a small offshore volcanic island located at the southernmost part of the Okinawa Trough. In this study, we conducted a detailed mapping incorporating the new high resolution LiDAR DTM laser scanning device to accurately construct a ...

Facies control on provenance shift during the early Cambrian transgression in Korea: Detrital zircon and geochemical evidence

open access: yesSedimentology, Volume 73, Issue 2, Page 418-440, February 2026.
ABSTRACT The early Cambrian transgression that flooded continental margins worldwide produced extensive sedimentary records that archive valuable information about palaeogeography and basin dynamics. This study integrates detrital zircon U–Pb geochronology and wholerock geochemistry from the Myeonsan and Myobong formations of the basal Taebaek Group ...

Receiver Function Imaging of the Crustal Structure Beneath Northern Taiwan Using Dense Linear Arrays

open access: yesGeosciences, 2022
In order to realize the crustal structure in Taiwan, the receiver function method was used to analyze the teleseismic waveforms recorded by two orthogonal broadband linear arrays deployed in northern Taiwan in the east–west and south–north directions by ...

B‐type olivine fabric and mantle wedge serpentinization beneath the Ryukyu arc [PDF]

open access: yesGeophysical Research Letters, 2013
Subduction is a fundamental Earth process, yet many aspects of subduction systems remain to be fully understood. Here we present anisotropic receiver function (RF) analysis to characterize the structure of the mantle wedge beneath the Ryukyu subduction zone.

Segmentation of the Izu-Bonin and Mariana slabs based on the analysis of the Benioff seismicity distribution and regional tomography results [PDF]

open access: yes, 2013
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 ...

Complex evolution and biogeographic history of moss‐inhabiting flea beetles from the Taiwan‐Ryukyu Island Arc (Coleoptera: Chrysomelidae: Alticini)

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
Extensive radiation of moss‐inhabiting flea beetles in Taiwan and Japan: The Ivalia uenoi complex displays high species diversity closely related to Japanese species. Complex biogeography revealed by phylogenomics: ddRAD data uncovered a history shaped by Miocene vicariance and Pliocene dispersal from Taiwan across the Taiwan‐Ryukyu archipelago ...

Slab horizontal subduction and slab tearing beneath East Asia [PDF]

open access: yes, 2019
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

Improving Global Radial Anisotropy Tomography: The Importance of Simultaneously Inverting for Crustal and Mantle Structure [PDF]

open access: yes, 2017
Observed seismic anisotropy gives the most direct information on mantle flow, but it is challenging to image it robustly at global scales. Difficulties in separating crustal from mantle structures in particular can have a strong influence on the imaging.

Cold Seep Communities in the Sea of Japan Are Species‐Poor and Dominated by a New Species of Provannid Snail

open access: yesJournal of Zoological Systematics and Evolutionary Research, Volume 2026, Issue 1, 2026.
The Sea of Japan is a semi‐enclosed marginal sea in the northwestern Pacific whose bathyal communities exhibit a depauperate species diversity due to anoxic events during the last glacial maximum. Cold seeps associated with chemosynthetic ecosystems were discovered in this region over three decades ago, yet their fauna have not been characterised. Here,
