At subduction zones, crustal material enters the mantle. Some of this material, however, is
returned to the overriding plate through volcanic and plutonic activity. Magmas erupted …

The transport of water from subducting crust into the mantle is mainly dictated by the stability
of hydrous minerals in subduction zones. The thermal structure of subduction zones is a key …

Fifteen andesite-dacite stratovolcanoes on the volcanic front of a single segment of the
Andean arc show along-arc changes in isotopic and elemental ratios that demonstrate large …

Water is a key ingredient in the generation of magmas in subduction zones. This review
focuses on the role of water in the generation of magmas in the mantle wedge, the factors …

Geophysics is a broad subject that encompasses not only the physics of the Earth, but also
the physics of the atmosphere and oceans. The heart of geophysics, however, is the theory …

Arc magmas and the continental crust share many chemical features, but a major question
remains as to whether these features are created by subduction or are recycled from …

Understanding mantle melting above subduction zones requires an evaluation of the
behaviour of elements for which the mantle contribution greatly exceeds any subduction …

Documenting the mass flux through convergent plate margins is important to the
understanding of petrogenesis in arc settings and to the origin of the continental crust, since …

Dehydration experiments on synthetic serpentine spiked with 11 trace elements (Cs, Rb, K,
Ba, Sr, La, Sm, Tb, Y, Yb and Nb) have been carried out at 12 kbar and 850° C to examine …

The phase relations of primitive magnesian andesites and basaltic andesites from the Mt.
Shasta region, N California have been determined over a range of pressure and …
