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 …
Students of a phenomenon as common but complex as andesite genesis often are overwhelmed by, or overlook, the volume and diversity of relevant information. Thus there is …
A map of the ocean basins (Fig. 5.1) shows that their most conspicuous topographic feature is the system of mid-oceanic ridges, the crests of which rise on average 1000-3000 m above …

The composition of chromian spinel in alpine-type peridotites has a large reciprocal range of Cr and Al, with increasing Cr#(Cr/(Cr+ Al)) reflecting increasing degrees of partial melting in …
We model 56 segments of subduction zones using kinematically defined slabs based on updated geometries from Syracuse and Abers (2006) to obtain a comprehensive suite of …
Recent diving with the JAMSTEC Shinkai 6500 manned submersible in the Mariana fore arc southeast of Guam has discovered that MORB‐like tholeiitic basalts crop out over large …
