Subduction zones not only return oceanic lithosphere into the mantle, but are also sites
where chemical components are transferred from the downgoing plate back to the surface in …

The geochemical signatures of subducting crust have been identified in various types of
mafic igneous rocks at convergent plate boundaries, where island arc basalts (IAB) and …

Much of our understanding of ocean ridges has come from the collection and analysis of
glasses recovered from ridge axes. However, applying the resulting methodologies to …

Arc magmas are important building blocks of the continental crust. Because many arc lavas
are oxidized, continent formation is thought to be associated with oxidizing conditions. On …

IGNEOUS ROCKS AND PROCESSES A practical introduction to igneous petrology for
students and practitioners The newly revised Second Edition of Igneous Rocks and …

Mantle oxygen fugacity exerts a primary control on mass exchange between Earth's surface
and interior at subduction zones, but the major factors controlling mantle oxygen fugacity …

The last 15yr have seen an explosion of data on the volatile contents of magmas parental to
arc volcanoes. This has occurred due to the intense study of melt inclusions trapped in …

Basaltic magmatism is a common feature of dynamically active terrestrial planets. The
compositions of basalts reflect the temperatures and pressures of magma generation …

The compositions of back-arc basin basalts (BABB) can usefully be viewed as products of
four factors:(1) the composition of inflowing mantle and its preconditioning during flow to the …

The Moon has long been thought to be highly depleted in volatiles such as water, and
indeed published direct measurements of water in lunar volcanic glasses have never …
