Serpentinites in subduction zones are important fluid reservoirs for crust-mantle interaction
and arc magma formation. The serpentinite-derived fluids can carry fluid-mobile elements …

Stable barium (Ba) isotopes are emerging as tracers for the recycling of crustal material into
the mantle. Small but significant Ba isotope variations have been found in global MORB (δ …

The origin of peralkaline granitic rocks with higher concentrations of alkali than Al 2 O 3 (with
molar (Na+ K)/Al> 1.0) is still debated. The debate focuses on whether they result from …

Altered oceanic crust (AOC) plays a critical role in geochemical recycling in subduction
zones. However, identifying contributions of subducted AOC to arc magmas remains a …

Barium (Ba) isotopes can be used as potential tracers for crustal material recycling in the
mantle. Determination of the Ba isotope composition of the depleted mantle is essential for …

Barium isotopes are a potential tracer of fluid-mediated recycling of subducted crustal
materials into the mantle wedge. However, the behavior of Ba isotopes during metamorphic …

Andesitic rocks have similar compositions to average continental crust and have played a
central role in improving our understanding of the formation and evolution of the continental …

Continental basalts commonly show ocean island basalts (OIB)-like geochemical
compositions, and their origin is geochemically linked to metasomatism of the big mantle …

Alkaline rocks crop out in subduction‐related volcanic arcs globally, whose genesis is
explained by partial melting of hybrid diapiric mélanges in the mantle wedge. Such a new …

Abstract High Ba-Sr granites are geochemically distinct from the more familiar I-, S-and A-
types (of igneous, sedimentary or anorogenic/anhydrous/alkaline parentage), in particular …
