We present bulk-rock and mineral Fe isotope data of ultramafic to mafic xenoliths and
basaltic to andesitic lavas from Adagdak Volcano (Adak Island, Central Aleutians) to study …

Fluids released from subducting slabs profoundly affect mantle composition, rock melting
points, and arc magma generation. However, identifying fluid sources (sediments, crust, or …

Serpentinite dehydration in subduction zones plays a pivotal role in geochemical cycling on
Earth. A number of geochemical studies on arc magmas have elucidated the contributions of …

Subduction zones are the key tectonic setting that links Earth's surficial sphere to deep
sphere (Zheng and Chen, 2016). Fluid action occurring in subduction zones is closely …

The mobility of redox sensitive elements such as iron, carbon and sulfur in subduction zone
fluids is important for redox transfer between the subducting slab and mantle wedge …

This study aims to uncover the evolving dynamics of element mobility in serpentinised
ultramafic clasts within the Asùt Tesoru mud volcano in the Mariana forearc. By employing in …

The isotopically light Fe signature of arc magmas relative to mid-oceanic ridge basalts
(MORB) is expected to be related to the redox state of their source. This implies a link …

The composition and redox state of the mantle wedge over geological time can be impacted
by fluid transfer from the slab during subduction. Although arc magmas are oxidised and …

The formation of marginal sea plate, through multi-stage arc rupture and back-arc spreading,
is a fundamental process in mature intra-ocean convergent plate margins. Identifying …

As a highly fluid mobile element, barium (Ba) and its isotopes are excellent tracers for fluid
associated processes in subduction zones. However, the behavior of Ba isotopes during …
