3D SR‐μXCT analysis for lithology detection: Application to Ryugu sample A0159
Meteoritics &Planetary Science, Volume 60, Issue 11, Page 2623-2654, November 2025.Abstract Extraterrestrial breccia samples are formed through impact‐related processes that combine the fragments of distinct lithologies. As such, they are valuable indicators of the complex formation and evolution history of planetesimals in our solar system.

The fall of the Haag (LL4‐6) chondrite breccia—Just 8 years after the nearby fall Stubenberg (LL6)
Meteoritics &Planetary Science, Volume 60, Issue 11, Page 2676-2702, November 2025.Abstract On October 24, 2024, an impressive fireball was visible over Austria. After the possible strewn field was calculated, the first sample of the Haag meteorite, with a mass of 8.76 g, was discovered on November 2, 2024, 8 days after the fireball event. Four more samples were found afterward putting the total sample mass at about 151 g.

Planetesimal Impact Vapor Plumes and Nebular Shocks Form Chondritic Mixtures
The Planetary Science JournalThe origin of chondrules and the chondritic sedimentary rocks that dominate the meteoritic record is a long-standing problem in planetary science. Here, we develop a physical model for the formation of chondritic mixtures as an outcome of vaporizing ...

Synthesis of Si-Fe Chondrule-like Dust Analogues in RF Discharge Plasmas
Applied SciencesChondrules are tiny particles that occur in stony meteorites and are considered as the building blocks of early asteroids and planets. It is believed that they were formed by the fast heating of the dust in the solar nebula.

Meteoritics &Planetary Science, Volume 60, Issue 11, Page 2655-2675, November 2025.Abstract We conducted a scanning electron microscopy (SEM) and transmission electron microscopy (TEM) study of sulfide–metal assemblages (SMAs) in minimally to moderately altered CR2 chondrites. The assemblages occur on chondrule rims and consist of kamacite cores rimmed by pyrrhotite.

Micromagnetic and microstructural analyses in chondrules of the Allende meteorite
Revista Mexicana de Ciencias Geológicas, 2018 Results of micromagnetic and microstructural studies of individual chondrules from the Allende carbonaceous meteorite are presented. Allende is a member of the CV3 carbonaceous chondrites, and part of the oxidized meteorites with iron in silicates and ...
