Geostandards and Geoanalytical Research, Volume 50, Issue 2, Page 341-367, June 2026.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.

An unsupervised machine learning approach to iron meteorite classification
Meteoritics &Planetary Science, Volume 61, Issue 6, Page 997-1011, June 2026.Abstract Iron meteorites are usually classified manually using bivariate elemental plots. This study extends iron meteorite classification into multi‐element space. We present a computational method for the classification of iron meteorites by applying unsupervised machine learning using density‐based cluster analysis.

Asteroids accretion, differentiation, and break-up in the Vesta source region: evidence from cosmochemistry of mesosiderites [PDF]
, 2022 The cosmochemistry of meteorites provides unique clues on asteroids accretion, differentiation, collisional break-up and reassembly - processes of critical importance for understanding planet formation in the early solar system.

Experimental cosmochemistry in the Space Station [PDF]
, 1987 The purpose of two workshops was to identify and discuss experiments in cosmochemistry that cannot be conducted under the conditions available in terrestrial laboratories, but may be carried out successfully in the proposed Space Station.

Ryugu reference project: Recommendations from the measurement definition team
Meteoritics &Planetary Science, Volume 61, Issue 5, Page 819-848, May 2026.Abstract Sample return missions play a significant role in planetary science by providing pristine extraterrestrial materials. JAXA's Hayabusa2 and NASA's OSIRIS‐REx missions have returned samples from the C‐type asteroids Ryugu and Bennu, respectively. The chemical and mineralogical compositions of these samples closely resemble those of CI chondrites,

Non‐innocent solvents in meteorite extractions: Evidence for artifact formation
Meteoritics &Planetary Science, Volume 61, Issue 4, Page 706-719, April 2026.Abstract Solvent extraction is a cornerstone of meteoritic organic and inorganic chemistry, yet the assumption that common solvents act as chemically inert media is becoming increasingly untenable. This study reports that low‐molecular‐weight alcohols, particularly methanol and ethanol, are “non‐innocent” solvents when used to extract soluble sulfur ...
