Experimental investigation of the fluid driven carbonation of serpentinites and spinel-peridotites: implications for the carbon and trace element cycle in the forearc region of the mantle wedge
… (C) are released from the subducting slab into fluids, but less carbon is outgassed in arc volcanoes implying the storage of C in the mantle wedge. This experimental study investigates the fate of C bearing aqueous fluids when they travel through the (partially) hydrated forearc mantle targeting …

Fluid-mobile element cycling (halogens, boron, lithium) and sourcing through the Costa Rican convergent margin
The source of fluids in convergent margins can be traced using fluid-mobile elements such as Cl, Br, I, B, and Li. However, previous studies have often overlooked the forearc. Describing fluid loss from subducting oceanic crust to the forearc is difficult for several reasons including differences …

Mantle Wedge Evolution beneath the Northern Mariana Forearc
… Mariana trench wall. High concentration of fluid mobile elements (Ba, Th, La, Sr, and U) in the bulk rock indicates interaction of slab-derived fluids with the mantle wedge. Major element analyses of primary minerals reveal a wide range of variations in the Cr# of spinels from 0.28-0.83 …

Petrology and geochemistry of Sangeang Api and recent volcanism in the Sumbawa-Flores sector of the Sunda Arc: the response of along-arc geochemistry to subduction processes.
… of arc magmas; enrichment in LREE, alkali-earth elements and Sr, depletion in Nb, Ta, Zr and Ti and high U/Th. They are also enriched in fluid-mobile elements (Cl, Ba, Cs, etc.). The cumulate xenoliths are separated into two distinct groups; the cpx+mgt and cpx+ol pyroxenites and the …

Adsorption–Desorption Reactions in the Weathering Zone: Implications for Silicate Weathering & the Carbon Cycle
… selectivity of alkali and earth-alkaline elements for the riverine adsorbed phase. These experiments utilised environmentally relevant adsorbent minerals and surface waters. By systematically varying the mineral-to-water ratio, reaction duration, and water chemistry, the experiments aimed …
