文摘
- •
In situ sulfide and bulk-rock analysis of S isotopes for Kimberley mantle peridotites.
- •
Limited isotope variability for in situ analyses (δ34S∼−6 to −1‰).
- •
Bulk-rock δ34S values overlap with average in situ results only if sulfides are fresh.
- •
The S isotopic composition of the sub-continental lithospheric mantle requires revision.
- •
Recycled ancient low-34S/32S sediments in the mantle source of metasomatic fluids.
