Secular Variation in the North American Kimberlite Formation: The Variable Connection to LLSVPs
Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.Abstract Kimberlites are rare and perplexing igneous rocks that may represent the deepest‐sourced melt type extracted from within the Earth's mantle, and their origin may be associated with Large Low Shear Velocity Provinces (LLSVPs) along the core‐mantle boundary.

The Role of the Overriding Plate and Mantle Viscosity Structure on Deep Slab Morphology
Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.Abstract Using 2D numerical subduction models, we compare the morphology of deep slabs in the presence of an oceanic or continental overriding plate and viscosity jumps at either 660 km or 1,000 km depth as suggested by the latest geoid inversions. We demonstrate that a continental plate, combined with a 1,000 km depth viscosity increase, promotes slab

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.Abstract The prominent arc‐continent collision zone in the Taiwan region is characterized by dual‐slab subduction systems, offering a unique window to investigate subduction polarity reversal (SPR) between the Eurasian and Philippine Sea plates, but the mechanism of this process in Taiwan is elusive because of complex subduction processes.

Interferometry from Space: A Great Dream
, 2014 During some thirty years, 1980-2010, technical studies of optical interferometry from instruments in space were pursued as promising for higher spatial resolution and for higher astrometric accuracy.

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.Abstract The first joint inversion of local and teleseismic waveform spectra data is conducted to determine 3‐D P and S wave attenuation (Q) tomography of the Japan subduction zone down to 700 km depth. We develop a novel technique to reliably estimate the corner frequency and attenuation factor from the observed spectra of seismograms.
