MORB mantle and subduction components interact to generate basalts in the southern Mariana Trough back-arc basin
TLDR
The results of the first geochemical and isotopic survey of basaltic glasses dredged along the spreading ridge of the southern Mariana Trough (SMT; 15-17°N) are reported in this paper.About:

Hafnium isotope evidence for ‘conservative’ element mobility during subduction zone processes
TL;DR: In this paper, a detailed Hf isotope study of oceanic arc lavas and paired arc/back-arc settings has been conducted and it was shown that the high field strength elements are always displaced significantly from their co-existing back-arc spreading centres which can be considered to sample the local mantle.

Geochemical mapping of the Mariana arc‐basin system: Implications for the nature and distribution of subduction components
TL;DR: In this article, a new ICP-MS database for glasses from the Mariana Trough was used to provide the basis for a geochemical mapping of the arc-basin system.

Origin of Back‐Arc Basin Magmas: Trace Element and Isotope Perspectives
Julian A. Pearce,Robert J. Stern +1 more
TL;DR: The back-arc basin basalts can usefully be viewed as products of four factors: (1) the composition of inflowing mantle and its preconditioning during flow to the site of melting; (2) the influx of a subduction component into the arc-basin system; (3) the nature of the interaction between the mantle and subduction components; (4) the melting of water-rich mantle and the assimilation/ crystallization history of the resulting hydrous magma.

Back-arc basin basalt systematics
Brian Taylor,Fernando Martinez +1 more
TL;DR: In this paper, a positive correlation between the average degree and pressure of mantle melting that reflects regional variations in mantle potential temperatures (Lau/Manus hotter than Mariana/Scotia) was found.

An Overview of the Izu‐Bonin‐Mariana Subduction Factory
TL;DR: The Izu-Bonin-Mariana (IBM) arc system extends 2800km from near Tokyo, Japan to Guam and is an outstanding example of an intra-oceanic convergent margin (IOCM) as mentioned in this paper.

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.

Tectonic Implications of the Composition of Volcanic Arc Magmas
Julian A. Pearce,David W. Peate +1 more
TL;DR: In this paper, the authors summarize knowledge of the behavior of elements in the subduction system and highlight the physical and chemical processes that have been invoked as being important in controlling the composition of volcanic arc magmas.
