Volatile elements (water, carbon, nitrogen, sulfur, halogens, and noble gases) played an
essential role in the secular evolution of the solid Earth and emergence of life. Here we …

Basalt geochemistry can be used as a diagnostic indicator for determining the tectonic
setting of origin, because specific plate tectonic settings often impart distinctive geochemical …

A recent global compilation of the thermal structure of subduction zones is used to predict
the metamorphic facies and H2O content of downgoing slabs. Our calculations indicate that …

How serpentinites in the forearc mantle and subducted lithosphere become involved in
enriching the subarc mantle source of arc magmas is controversial. Here we report …

Subduction initiation is one of the least understood aspects of plate tectonics. In an effort to
obtain the first in situ magmatic record of subduction initiation, the International Ocean …

A first-order observation of convergent margin volcanism is that continental arc
stratovolcanoes have substantially elevated incompatible element abundances and notable …

To better understand the evolutionary history of the African continental crust, a combined U–
Pb, Lu–Hf and O isotopic study has been carried out by in situ analyses of approximately …

Molybdenum isotope variations in mafic arc lavas have mainly been attributed to the
influence of slab-derived components, such as subducted sediment melts and aqueous …

Discovery of seafloor volcanism west of Buldir Volcano, the westernmost emergent volcano
in the Aleutian arc, demonstrates that surface expression of active Aleutian volcanism falls …

Supra-subduction zone (SSZ) ophiolites such as the Troodos Ophiolite of Cyprus are
thought to have formed at spreading centres close to subduction zones. Similarities in the …
