Rapid terrestrial weathering of the CI1 carbonaceous chondrite find Oued Chebeika 002
Meteoritics &Planetary Science, Volume 61, Issue 2, Page 211-223, February 2026.Abstract Alteration of historic CI1 meteorite falls during their curation demonstrates the susceptibility of smectite‐rich carbonaceous chondrites to terrestrial exposure. The discovery of Oued Chebeika 002 in Morocco in June 2024 presents a unique opportunity to document the earliest stages of weathering of a CI1 find.
