Lithium isotopic composition of marine sediments
To understand the role of subducted sediment in arc magmatism and the formation of the continental crust, we have determined the Li isotopic composition of marine sediments subducting at several

The return of subducted continental crust in Samoan lavas
TLDR
The geochemical evidence from these Samoan lavas significantly redefines the composition of the EM2 (enriched mantle 2; ref. 9) mantle endmember, and points to the presence of an ancient recycled upper continental crust component in the Samoan mantle plume.
Recycling of Marine Carbonate Induced Calcium Isotope Heterogeneity of Arc Magmas in Subduction Zones
Calcium (Ca) is an essential element constituting sedimentary carbonate in subducting sediments. Ca isotopic characteristics of subduction-related rocks could provide insight into the behavior and
Chemical fluxes in the Tonga Subduction Zone: Evidence from the Southern Lau Basin
Chemical and isotopic data for volcanic glasses from the Valu Fa Ridge (VFR) in the southern Lau Basin closely resemble the composition of volcanics from the nearby Tonga arc. The most primitive
The Architecture, Chemistry, and Evolution of Continental Magmatic Arcs
Continental magmatic arcs form above subduction zones where the upper plate is continental lithosphere and/or accreted transitional lithosphere. The best-studied examples are found along the western
Hf‐Nd input flux in the Izu‐Mariana subduction zone and recycling of subducted material in the mantle
In subduction zones, two major mass fluxes compete: the input flux of altered oceanic crust and sediments subducted into the mantle and the output flux of magma that forms the volcanic arc. While the

Crustal recycling and the Aleutian arc
Tracing trace elements from sediment input to volcanic output at subduction zones
AT ocean trenches, sea-floor sediments may either be scraped off the subducting plate, or accompany it into the mantle. Some of the subducted sediment may then be recycled to the arc crust by
Nature and composition of the continental crust: A lower crustal perspective
Geophysical, petrological, and geochemical data provide important clues about the composition of the deep continental crust. On the basis of seismic refraction data, we divide the crust into type
Geochemical Variations in Vanuatu Arc Lavas: the Role of Subducted Material and a Variable Mantle Wedge Composition
New compositional data are presented for recent (<3.5 Ma) basaltic lavas from the Vanuatu arc and North Fiji back-arc, and for material being subducted at the Vanuatu trench. Sr, Nd and Pb isotope

TLDR
The magmas being produced at active arcs cannot be used as a model for the development of most of the Earth’s continental areas, due to weak correlations with global correlations of variations between arc magma characteristics and regional geological parameters.
