As subducting plates reach the base of the upper mantle, some appear to flatten and
stagnate, while others seemingly go through unimpeded. This variable resistance to slab …

A stagnant slab is a subducted slab of oceanic lithosphere subhorizontally deflected above,
across, or below the 660 km discontinuity. This phenomenon has now been widely …

The temperature at the 410-km discontinuity is re-evaluated by comparing the depth of the
discontinuity with the olivine–wadsleyite transition pressure obtained using in situ X-ray …

Semiempirical equations of state (EoS) of Au, Pt, MgO, NaCl-B1, and NaCl-B2 based on
expanded Mie–Grüneisen–Debye approach, which are consistent both with the Mie …

Cold, dense subducting lithosphere provides the primary force driving tectonic plates at
Earth's surface. The force available to drive the plates depends on a balance between the …

Variable morphologies of subducting slabs are observed in tomographic images of the
mantle transition zone (MTZ), where slabs appear to stagnate in the MTZ or enter the lower …

Water is transported into the deep mantle via hydrous minerals in subducting slabs. During
subduction, a series of minerals in these slabs such as serpentine or chlorite, Mg–sursassite …

We determined phase relations of harzburgite and basalt (mid‐ocean ridge basalt, MORB)
at 12–28 GPa and 1600–2200° C with a large number of experiments using a multianvil …

The 660-kilometre seismic discontinuity is the boundary between the Earth's lower mantle
and transition zone and is commonly interpreted as being due to the dissociation of …

With changing pressure and temperature conditions, downwelling and upwelling crustal and
mantle rocks experience several solid–solid phase transitions that affect the mineral …
