Constraints on mantle melting and composition and nature of slab components in volcanic arcs from volatiles (H 2 O, S, Cl, F) and trace elements in melt inclusions from the Kamchatka Arc
TLDR
In this paper, the authors evaluate the combined systematics of volatiles (H2O, S, Cl, F) and incompatible trace elements in their parental magmas and mantle sources to constrain thermal conditions of mantle melting, and estimate the composition of slab-derived components.About:

Special Paper: Adakite-Like Rocks: Their Diverse Origins and Questionable Role in Metallogenesis
TL;DR: The case for these petrogenetic models for adakites and high Mg andesites is best made in the Archean, when higher mantle geotherms resulted in subducting slabs potentially reaching partial melting temperatures at shallow depths before dehydration rendered the slab infusible as mentioned in this paper.

Magmatic to hydrothermal metal fluxes in convergent and collided margins
TL;DR: In this article, the authors examined the source of normal arc magmas and concluded that they are predominantly derived from partial melting of the metasomatized mantle wedge, with possible minor contributions from subducted sediments.

Sediment Melts at Sub-arc Depths: an Experimental Study
Joerg Hermann,Carl Spandler +1 more
TL;DR: The phase and melting relations in subducted pelites have been investigated experimentally at conditions relevant for slabs at sub-arc depths (T¼600^10508C, P¼25^45 GPa) as discussed by the authors.

Why do mafic arc magmas contain ∼4wt% water on average?
TL;DR: In this article, the authors studied the H2O contents of the least degassed melt inclusions from each volcano and found that the mean and common average values for H2Os are within one s.d.

Accessory phase control on the trace element signature of sediment melts in subduction zones
Joerg Hermann,Daniela Rubatto +1 more
TL;DR: In this article, the trace element liberation from metapelites in the range of 2.5-4.5 GPa and 750-1050°C was studied.

Chemical and isotopic systematics of oceanic basalt : implications for mantle composition and processes
TL;DR: In this article, trace-element data for mid-ocean ridge basalts and ocean island basalts are used to formulate chemical systematics for oceanic basalts, interpreted in terms of partial-melting conditions, variations in residual mineralogy, involvement of subducted sediment, recycling of oceanic lithosphere and processes within the low velocity zone.

Chemical differentiation of the Earth: the relationship between mantle, continental crust, and oceanic crust
TL;DR: In this paper, the average chemical compositions of the continental crust and the oceanic crust (represented by MORB), normalized to primitive mantle values and plotted as functions of the apparent bulk partition coefficient of each element, form surprisingly simple, complementary concentration patterns.

The chemical composition of subducting sediment and its consequences for the crust and mantle
Terry Plank,Charles H. Langmuir +1 more
TL;DR: This article evaluated subducting sediments on a global basis in order to better define their chemical systematics and to determine both regional and global average compositions, and then used these compositions to assess the importance of sediments to arc volcanism and crust-mantle recycling, and to re-evaluate the chemical composition of the continental crust.
