Evidence for late impact‐induced metasomatism on the brachinite parent body recorded by a phosphate assemblage in NWA 7828

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Brachinites are a group of ultramafic achondritic meteorites thought to sample a planetesimal from the early inner solar system. They yield predominately ancient crystallization ages within 4 Ma of CAI formation, and while the formation mechanism for these samples is debated, they are widely thought to be partial melt residues from a ...

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

open access: yesMeteoritics &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

open access: yesMeteoritics &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

open access: yesMeteoritics &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 ...
