Recent studies on seismic imaging of the Northwest Pacific and East Asian region are
reviewed. High-resolution tomographic images reveal significant lateral heterogeneities in …

The subduction of marine carbonates and carbonated oceanic crust to the Earth's interior
and the return of recycled carbon to the surface via volcanism may play a pivotal role in …

To investigate the behavior of Mg isotopes during low-temperature alteration of oceanic
crust and to further understand its role in the global Mg cycle, we measured the Mg isotopic …

We determine high‐resolution 3‐D tomographic images of P‐wave isotropic velocity, radial
anisotropy and azimuthal anisotropy beneath NE Asia down to 800 km depth. Our results …

We report the first zinc isotope data (expressed as δ 66 Zn relative to the JMC-Lyon
standard) for chromian spinels (Cr-spinels) and coexisting olivines in oceanic peridotites. All …

Intraplate basaltic volcanism commonly exhibits wide compositional ranges from silica-
undersaturated alkaline basalts to silica-saturated tholeiitic basalts. Possible mechanisms …

Carbonatite metasomatism plays an important role in modifying the composition of Earth's
mantle, however, its effect on mantle Mg isotopic composition is poorly constrained. Here …

Nephelinites, a highly alkaline volcanic rock type, have widely been thought to be formed in
a shallow lithosphere previously impregnated with phlogopite and/or amphibole. Here we …

Dehydration of subducting oceanic crust and underlying serpentinized mantle is potentially
the most important source of fluids for element cycling between surface-processed materials …

Oceanic subduction zones are important channels for carbon exchange between the Earth's
crust and mantle. However, the nature of carbon cycles at depths from 120 to 410 km in the …
