Serpentinite dehydration during subduction releases fluids into the sub‐arc mantle, yet the
oxidizing capability of these fluids remains controversial. Here, redox‐sensitive Cu isotopes …

Arc basalts typically have higher Fe 3+/ΣFe ratios but lighter Fe isotopic compositions than
mid-ocean ridge basalts (MORB); however, the reasons for these differences are unclear …

Recent research on the water content of large igneous provinces (LIPs) has revealed that
water has a significant impact on the formation of LIPs. However, most studies focus on the …

This review describes the stable isotope character of the Earth's mantle, the 2900 km thick
silicate layer between the core and crust that comprises 67% of the Earth's mass and 84% of …

Hydration of the subduction zone forearc mantle wedge influences the downdip distribution
of seismicity, the availability of fluids for arc magmatism, and Earth's long term water cycle …

Serpentinite-derived components play an important role in chemical cycling in subduction
zones. However, it is difficult to identify recycled serpentinite in subarc mantle due to the …

High-pressure (HP) veins in eclogites are the products of fluid-rock interaction and provide
insight into the composition and evolution of fluids in subduction zones. We here present the …

Intra-crustal differentiation of primary arc magmas has been suggested to play an important
role in continental crust growth. Here we use the zinc (Zn) isotopic systematics of deep …

Recycling of upper crustal sediments through slab subduction contributes to sub‐continental
lithospheric refertilization and heterogeneity. However, the nature of recycled upper crustal …

Subduction zones (arcs and back-arcs) are major sites for elemental cycling via slab
dehydration and subsequent mantle metasomatism and melting; many models have been …
