Because of a combination of new observational tools and a flurry of large megathrust
earthquakes, tremendous progress has been made in recent years towards understanding …

Some of Earth's coldest mantle is found in subduction zones at the tip of the mantle wedge
that lies between the subducting and overriding plates. This forearc mantle is isolated from …

Owing to advances in microanalytical techniques over the last 15 years, there is a growing
database on the volatile contents of subduction-related magmas as recorded in melt (glass) …

A wide range of geophysical and geological data indicate that extensive serpentinization in
the forearc mantle is both expected and observed. Large volumes of aqueous fluids must be …

The two rock-forming polymorphs of serpentine Mg3Si2O5 (OH) 4, lizardite and chrysotile,
occur in nature in virtually identical ranges of temperature and pressure, from surficial or …

Processes in subduction zones such as slab and mantle‐wedge metamorphism, intraslab
earthquakes, and arc volcanism vary systematically with the age‐dependent thermal state of …

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 …

Rayleigh wave phase velocity maps from ambient noise and earthquake data are inverted
jointly with receiver functions observed at 828 stations from the USArray Transportable Array …

Understanding the physical properties of ultramafic rocks is important for evaluating the wide
variety of petrologic models for the Earth's upper mantle and lower oceanic crust. At …

In southern and central Alaska the subduction and active volcanism of the Aleutian
subduction zone give way to a broad plate boundary zone with mountain building and strike …
