Boron isotopes in boninites document rapid changes in slab inputs during subduction initiation
How subduction-related magmatism starts at convergent plate margins is still poorly
understood. Here we show that boron isotope variations in early-formed boninites from the …

Alteration enrichment of nitrogen in the gabbroic oceanic crust: Implications for global subducting nitrogen budget and subduction-zone nitrogen recycling
Uptake of nitrogen (N) during hydrothermal alteration of oceanic crust makes the altered
oceanic crust (AOC) a significant N reservoir in parallel to seafloor sediments. While N …
