Nature of slab-mantle interactions recorded by coupled δ13C–δ15N–δ18O signatures and elemental compositions of Koidu diamonds and their inclusions

Lai, Mei Yan, Stachel, Thomas, Stern, Richard A., Li, Kan, Pearson, D. Graham, Harris, Jeff W.
Abstract Eclogitic diamond formation can be associated with interactions between subducted slabs and ambient mantle. To gain a better understanding of the extent of chemical exchange between slabs and ambient mantle and the mechanisms of coeval diamond formation, we examined 16 diamonds with...

Quantification of nitrogen in subducting slabs and its recycling in the forearc and sub-arc regions
DownloadSpring 2023
Nitrogen, a life-essential element, is exchanged between Earth’s surface and interior through subduction, which has been acting as a dominant driving force regulating the long-term evolution of Earth’s major N reservoirs. However, the nitrogen input fluxes into global subduction zones and the...
