TLDR
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 nature of element migration processes in the upper mantle beneath volcanic arcs.About:

An overview of adakite, tonalite–trondhjemite–granodiorite (TTG), and sanukitoid: relationships and some implications for crustal evolution
TL;DR: In this article, an analysis of an extensive adakite geochemical database identifies two distinct compositional groups: high-SiO2 adakites (HSA) which represent subducted basaltic slab-melts that have reacted with peridotite during ascent through mantle wedge and low-Si O 2 adakitic mantle wedge.
Journal ArticleDOI
Adakitic magmas: modern analogues of Archaean granitoids
TL;DR: Sajona et al. as mentioned in this paper showed that the liquids produced by melting of tholeiite in subduction-like P-T conditions are adakitic in composition, indicating that modern adakites have trondhjemitic affinities (high Na2O contents and K2O/Na2O∼0.5) and their Mg no.

A model for Trondhjemite-Tonalite-Dacite Genesis and crustal growth via slab melting: Archean to modern comparisons
Mark S. Drummond,Marc J. Defant +1 more
TL;DR: In this paper, the authors introduced the importance of subducted oceanic crustal age on arc petrogenesis and demonstrated that Archean TTD crustal generation processes are also present in selected high-Al Phanerozoic TTD terranes.
Journal ArticleDOI
Geochemical and geodynamical constraints on subduction zone magmatism
TL;DR: In this article, a quantitative model has been developed for IAB petrogenesis with the transfer of trace elements from the slab to the mantle wedge being modelled with empirical slab-fluid partition coefficients whilst the mantlewedge to arc-crust transfer is constrained by melt-solid partitioning.
Journal ArticleDOI
Element transport from slab to volcanic front at the Mariana arc
TL;DR: Agarwal et al. as mentioned in this paper presented a comprehensive geochemical data set for the most recent volcanics from the Mariana Islands, which provides new constraints on the timing and nature of fluxes from the subducting slab.

Trace element fractionation during anatexis
TL;DR: The theoretical basis of trace element fractionation presented in a paper by P. W. Gast (1968) can be developed in a more flexible algebraic form, which is described and illustrated in this article.

Chemical characteristics of island-arc basalts: Implications for mantle sources
TL;DR: In this article, the major-element, trace-element and isotopic compositions of approximately 1200 basalts (Mg +Fe 2+ ) > 65 ] IAB and MORB are similar, but differ significantly from IPB.

The mineralogy, geochemistry and origin of Iherzolite inclusions in Victorian basanites
Frederick A. Frey,David H. Green +1 more
TL;DR: The mineralogy of Iherzolite inclusions in Victorian basanites indicates an upper mantle origin, but a range of temperatures from igneous to metamorphic (subsolidus) is indicated by the mineral compositions as discussed by the authors.
