Matera: A not so ordinary H5 chondrite breccia with very low density and high porosity

Meteoritics &Planetary Science, EarlyView.
Abstract On the evening of February 14, 2023, at 17:58 UT, a fireball was detected by three cameras of the Italian PRISMA network (FRIPON network). The first samples of the Matera meteorite, collected 3 days after the fall, lay on the balcony of a private home.

The sub‐μm petrography of the observed meteorite fall Winchcombe—A complex array of pristine and altered chondrite components

Meteoritics &Planetary Science, EarlyView.
Abstract Samples of observed meteorite falls provide important constraints on alteration histories of Solar System materials. Due to its rapid collection, terrestrial alteration in the observed Mighei‐type (CM) carbonaceous chondrite fall Winchcombe was minimal.

Olivine fabric and microstructure in Northwest Africa (NWA) 7059 and Nova 018: Insights into ureilite deformation

Meteoritics &Planetary Science, EarlyView.
Abstract Olivine is a major constituent in ureilites and commonly defines macroscopic fabric via shape‐preferred orientation of elongate grains. In this study, we examined olivine fabric (crystallographic preferred orientation, or CPO) and microstructures in the unbrecciated olivine‐pigeonite ureilites Northwest Africa (NWA) 7059 and Nova 018 using ...

Cosmic ray exposure ages and pre‐atmospheric shielding of Omani meteorites: Implications for 14C and 14C/10Be terrestrial ages of meteorites from hot and cold deserts

Meteoritics &Planetary Science, EarlyView.
Abstract We present isotope concentrations of the light noble gases He and Ne for samples from five well‐documented strewnfields and two individual meteorites from the Omani desert. Cosmogenic (22Ne/21Ne)cos for the strewnfield samples are low, as expected considering the total known masses.
