Key Points We recommend using the notation δ122/118SnNIST SRM 3161a for mass‐dependent Sn isotope data. We derived conversion factors relative to NIST SRM 3161a for Puri Sn CEZA (0.132 ± 0.011‰), Sn Lyon (0.229 ± 0.016‰), Sn IPGP (0.162 ± 0.018‰). Tin isotope compositions are presented for SPEX CertiPrep Sn and nine USGS reference materials.

Combustion and Pyrolysis EA‐IRMS Techniques to Determine the δ2H of Diamonds
ABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.

Abstract Dense sedimentary iron formations (IFs) subducted into the mantle during Earth's early history, may have descended to the core‐mantle boundary where they could exert strong control on its thermal and seismological properties. A key unanswered question is the extent to which IFs retain their oxidized character in the much more reducing mantle ...
