In situ single‐spot Rb/Sr cosmochronology of roedderite in the Ribbeck aubrite (asteroid 2024 BX1)

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The mineralogy and textures of several fragments from the Ribbeck aubrite were analyzed using a combination of scanning electron microscopy, electron microprobe analysis, μRaman spectroscopy, and laser ablation inductively coupled reaction cell mass spectrometry (LA‐ICP‐MS/MS).

CI chondrite Oued Chebeika 002 links asteroids Bennu and Ryugu to common parent body

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract CI chondrites are a compositionally primitive group of meteorites that have undergone extensive aqueous alteration, providing insights into the evolution of primitive planetesimals. Oued Chebeika 002 is the most pristine CI chondrite to date.

Ryugu Reference Project: Recommendations from the Measurement Definition Team

open access: yesMeteoritics &Planetary Science, EarlyView.
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,

Confirming the impact origin of the São Miguel do Tapuio structure, northeastern Brazil

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The São Miguel do Tapuio structure (SMT) is a remarkable, nearcircular feature of about 21 km diameter, centered at 5°37.6′ S, 41°23.3′ W in Piauí state, northeastern Brazil. The structure is located within the sedimentary strata of the Paleozoic–Mesozoic Parnaíba Basin and predominantly comprises sandstones of the Devonian Pimenteiras and ...

The effect of terrestrial weathering on the mineralogy and petrologic (sub)types of CM chondrites explored by kinetic modeling and laboratory experiments

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Terrestrial weathering alters the chemical and isotopic composition, and mineralogy, of meteorites; its effects on ordinary chondrites are well‐studied, but relatively little is known about the susceptibility of carbonaceous chondrites. We combined laboratory experiments, whereby Chwichiya 002 (C3‐ung find), Murchison (CM2 fall) and Kolang ...
