The lzu-Bonin-Mariana (IBM) arc system extends 2800km from near Tokyo, Japan to Guam
and is an outstanding example of an intraoceanic convergent margin (IOCM). Inputs from …

Much progress has been made over the past several decades in delineating the structure of
subducting slabs, but several key aspects of their dynamics remain poorly constrained …

Magnetotelluric exploration has shown that the middle and lower crust is anomalously
conductive across most of the north-to-south width of the Tibetan plateau. The integrated …

Subducting slabs provide the main driving force for plate motion and flow in the Earth's
mantle,,,, and geodynamic, seismic and geochemical studies offer insight into slab dynamics …

It is well recognized that active arc volcanism at nearly all subduction zones requires
temperatures greater than 1200° C in the subarc mantle, despite the underthrusting cool …

A variety of atypical plume-like structures and focused upwellings that are not rooted in the
lower mantle have recently been discussed, and seismological imaging has shown …

Subduction of tectonic plates limited in lateral extent and with a free‐trailing tail, ie,“free
subduction,” is modeled in a three‐dimensional (3‐D) geometry. The models use a …

The direction of tectonic plate motion at the Earth's surface and the flow field of the mantle
inferred from seismic anisotropy are well correlated globally, suggesting large-scale …

The present kinematics in the eastern Mediterranean and Middle East is now well
constrained by GPS measurements and dominated by a circular counterclockwise motion …

Results of fluid dynamical experiments are presented to model the kinematics of lithospheric
subduction in the upper mantle. The experiments model a dense high‐viscosity plate …
