Subduction zones are where sediments, oceanic crust, and mantle lithosphere return to and
reequilibrate with Earth's mantle. Subduction zones are interior expressions of Earth's …

The concentration and distribution of water in the Earth has influenced its evolution
throughout its history. Even at the trace levels contained in the planet's deep interior (mantle …

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 …

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 physical and chemical properties of magma govern the eruptive style and behaviour of
volcanoes. Many of these parameters are linked to the storage pressure (P) and temperature …

The Mariana, east Scotia, Lau, and Manus back-arc basins (BABs) have spreading rates that
vary from slow (< 50 mm/yr) to fast (> 100 mm/yr) and extension axes located from 10 to 400 …

Miyashiro (1973) famously initiated a debate on the tectonic setting of ophiolite complexes
by proposing that 'the Troodos ophiolitic complex was probably formed in an island arc'. This …

A total of 145 inclusions, trapped and isolated in Mg-rich olivine phenocrysts (Fo0. 87–0.94)
from basalts and ultramafic lavas, and representing the most primitive mantle melts known …

We report here a detailed mineralogical, geochemical, and experimental study of a high-Ca
boninite suite from the northern termination of the Tonga trench. Most samples are strongly …

We report the results of a geochemical and isotopic study of mostly basaltic glasses
recovered from 25 dredge stations along the northernmost 500 km of the Mariana Trough …
