Within the upper mantle, the seismic discontinuity at 410-km depth marks the top of the
transition zone and is attributed to pressure-induced transformation of olivine into wadsleyite …

In the Japan subduction zone, a locally depressed 660 discontinuity has been observed
beneath northeast Asia, suggesting downwelling of materials from the mantle transition zone …

To understand the effect of hydration on the sound velocities of major mantle minerals and to
constrain the mantle's H2O budget, we have measured the single-crystal elastic moduli of …

It is well known that anelasticity has significant effects on the propagation of seismic waves,
as manifested by physical dispersion and dissipation. Investigations of anelasticity provide …

The onset of hydrous partial melting in the mantle above the transition zone is dictated by
the H 2 O storage capacity of peridotite, which is defined as the maximum concentration that …

With P‐to‐S converted waves recorded at seismic stations of the US Transportable Array, we
image the fine structure of upper mantle and transition zone (TZ) beneath the western US …

The mantle transition zone has been considered a major water reservoir in the deep Earth.
Mass transfer across the transition-zone boundaries may transport water-rich minerals from …

Waveforms of SS precursors recorded by global stations are analyzed to investigate lateral
heterogeneities of upper mantle discontinuities on a global scale. A sporadic low‐velocity …

Shear wave impedance discontinuities are inventoried for eight paths connecting circum‐
Pacific earthquakes with seismic stations on Hawaii and Oahu. In addition to the transition …

Increasing evidence shows that the low-velocity layer (LVL) atop the mantle transition zone
(MTZ) may play a critical role in Earth's evolution. The existence and formation of the LVL in …
