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 …

The compositions of ocean island basalts (OIB) can record signatures of ancient subducted
crust that has been recycled through the mantle. Based on their radiogenic isotope, major …

This study presents Ba isotope compositions of ocean island basalts (OIB) from the Azores
Archipelago to investigate the origin of the enriched components within their mantle sources …

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 …

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

Rubidium is a moderately volatile element with high incompatibility and fluid mobility. Its
stable isotopes have great potential in tracing various geological processes. For example …

Stable strontium and barium isotopes are potential tracers for understanding planetary
differentiation and the nature of the building blocks of terrestrial planets. Strontium and …

Most primary tin deposits are intimately associated with highly-fractionated granites (HFGs),
but the factors controlling the formation of tin mineralization; including source enrichment …
