New Magnetite Reference Material for SIMS δ18O Measurements and a Study of Precision and Accuracy Due to Crystal Orientation Effects

Geostandards and Geoanalytical Research, EarlyView.
Key Points A new magnetite reference material (PF21mt) is available for δ18O measurements by SIMS. Reproducibility of measurement results in two laboratories suggest orientation bias of ±2‰ (2s) at 20 keV. Repeatability improves to ±1‰ (2s) when using a 13 keV protocol, suggesting reduced orientation bias. In situ isotope ratio measurements provide the

New Potential Haematite and Magnetite Reference Materials for Iron Isotope Measurements by Solution Nebulisation MC‐ICP‐MS and by In Situ ns‐LA‐MC‐ICP‐MS

Geostandards and Geoanalytical Research, EarlyView.
Key Points Two haematite and magnetite materials were developed as potential Fe isotope reference materials. Solution and in situ LA‐MC‐ICP‐MS analyses yielded consistent δ56Fe values. Both materials are isotopically homogeneous and suitable for in situ Fe isotope calibration.

Location, Location, Location: Monazite Behaviour During UHT Metamorphism and Melt Crystallization

Journal of Metamorphic Geology, EarlyView.
ABSTRACT Monazite is a robust mineral for recording the suprasolidus evolution of migmatites and granulites. However, monazite commonly has diverse compositions and yields variable dates in a single sample; understanding the controls on monazite behaviour and composition during partial melting and melt crystallization are not always straightforward ...

Noble gases and nitrogen in material from asteroid Bennu

Meteoritics &Planetary Science, EarlyView.
Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.
