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 …
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 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 …

To investigate the behaviour of Ba isotopes during carbonatite petrogenesis and to explore the possibility of using carbonatites to constrain the Ba isotopic composition of the mantle …
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 …

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 …

As surface reservoirs (eg sediments and altered oceanic crust) have extremely high barium (Ba) concentrations and distinctive Ba isotope compositions compared to the mantle, Ba …
