Anisotropic tomography and dynamics of the big mantle wedge
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 …

Upper mantle scale enrichment of Cenozoic intraplate magmatism in Northeast Asia: He-Sr-Nd-Pb-O isotope geochemistry of the basalts around the Korean peninsula
The Earth's mantle is considered to be geochemically heterogeneous, which is reflected by
the diverse compositions of oceanic island basalts (OIB). The mantle enrichment resulting in …

Volcanism at the end of continental rifting: The Cretaceous syn-rift to post-rift transition in the Songliao Basin (NE China)
The evolution of volcanism at the latest stages of continental rifting and its transition to the
post-rift stage are poorly known. A Cretaceous rifting episode characterized the Songliao …
