Geochemical and petrographic re‐evaluation of ungrouped iron meteorites from Western Australia

Meteoritics &Planetary Science, Volume 61, Issue 3, Page 444-465, March 2026.
Abstract Under the current classification scheme, ungrouped irons make up ~11% of all recognized iron meteorites. A further ~7% of iron meteorites are currently classified as simply “irons” and are yet to be fully classified. To potentially classify these meteorites, newer approaches, including either statistical modeling or advanced geochemical ...

Shock metamorphic effects in Itokawa phosphates: A comparison with megaregolith‐derived meteorites

Meteoritics &Planetary Science, Volume 61, Issue 3, Page 351-370, March 2026.
Abstract Returned regolith samples from the asteroid Itokawa provide a unique opportunity to compare shock metamorphic effects in unconsolidated regolith materials with those preserved in lithified meteorites, that is, megaregolith. We analyzed four Itokawa particles (Ueda—RA‐QD02‐0519, Narahara—RA‐QD02‐0573, Domon—RA‐QD02‐0588, Ishiuchi—RX‐MD03‐0212 ...

Experimental Observation of a Calcium Silicon Double Carbonate

Angewandte Chemie, Volume 138, Issue 9, 23 February 2026.
High‐pressure and ‐temperature reactions between Ca5(Si2O7)(CO3)2 tilleyite and CO2 carbon dioxide yield the first experimental evidence of the double carbonate Ca2Si(CO3)4 and a new Ca2(C4O10) phase containing tetrahedral [CO4] units. These findings reveal unexpected carbonate chemistry and highlight pathways for carbon incorporation under mantle ...

Al‐Khadhaf: The first camera‐observed (H5–6) meteorite fall from Oman

Meteoritics &Planetary Science, Volume 61, Issue 3, Page 522-547, March 2026.
Abstract A fireball camera system installed in 2022 by the Oman Meteorite Monitoring Project (OMMP) as part of the Global Fireball Observatory (GFO) recorded a 3.2 s fireball on March 8, 2022 at 8:15 p.m. UTC. A meteoroid of 4 ± 2 kg entered the atmosphere at 14.0 km/s.
