Kindberg, the fifth meteorite fall in Austria: A weakly shocked L6 chondrite breccia with high‐pressure phases

Meteoritics &Planetary Science, Volume 61, Issue 1, Page 17-38, January 2026.
Abstract A bright fireball was seen at 4:46 a.m. CET on November 19, 2020, over Austria, and also eye witnessed in Italy and Germany. The resulting Kindberg meteorite was the fifth well‐approved meteorite fall in Austria, and all rocks represent ordinary chondrites.

Textural and geochemical diversity of impact melt rock clasts in Apollo 16 sample 67015: Implications for the provenance of impact ejecta in the lunar highlands

Meteoritics &Planetary Science, Volume 61, Issue 1, Page 39-63, January 2026.
Abstract Apollo sample 67015 has been classified as a fragmental breccia comprised of highlands‐type clasts and is proposed to be the most complex Apollo 16 sample. 67015 is dominated by impact melt rock clasts that display a variety of textures, which have been previously interpreted to be indicative of multiple impact events.

Reproduction Experiments of Radial Pyroxene Chondrules Using a Gas-jet Levitation System under Reduced Conditions

The Astrophysical Journal
Reproduction experiments of radial pyroxene (RP) chondrules were carried out using an Ar–H _2 or Ar gas-jet levitation system in a reducing atmosphere in order to simulate chondrule formation in the protoplanetary disk.

Nondestructive analysis of Bennu samples toward comparative studies with Ryugu samples

Meteoritics &Planetary Science, Volume 61, Issue 1, Page 3-16, January 2026.
Abstract Analyzing primitive extraterrestrial samples from asteroids is key to understanding the evolution of the early solar system. The OSIRIS‐REx mission returned samples from the B‐type asteroid Bennu, providing a valuable opportunity to compare them with the Ryugu samples collected by the Hayabusa2 mission.

Description and modeling of the Jiddat al Harasis 091 L5 strewn field

Meteoritics &Planetary Science, Volume 61, Issue 1, Page 107-121, January 2026.
Abstract With a size of 51.2 × 7.2 km, the 10.9 ± 1.7 ka old Jiddat al Harasis 091 L5 chondrite strewn field is the largest known in Oman. It consists of more than 700 meteorites with a total mass of >4.5 tons from which the largest six stones of >100 kg to 1.5 tons make up two thirds of the total mass.

Modeling enstatite chondrites: Reduced rocks with a pinch of oxidized material (affected by varying H2O(g)) derived from planetesimals shocked during the epoch of giant–planet migration

Meteoritics &Planetary Science, Volume 61, Issue 1, Page 122-139, January 2026.
Abstract The O‐, N‐, Mo‐, Ru‐, Os‐, Cr‐, Ti‐, Ni‐, Fe‐, Nd‐, Ca‐, Zn‐, Sr‐, and Mg‐isotopic compositions of enstatite chondrites are essentially identical to those of the Earth and Moon. These correspondences suggest enstatite chondrites formed at ≈1 AU as the only known chondrite groups that accreted in the vicinity of a major planet. Bulk Earth has a

Occurrence and characterization of nanosulfide‐rich regions on asteroid Ryugu: Insights from mackinawite and pyrrhotite

Meteoritics &Planetary Science, Volume 61, Issue 1, Page 168-181, January 2026.
Abstract Samples returned from asteroid Ryugu by the Hayabusa2 mission are dominated by fine‐grained matrix material made of phyllosilicates and nanosulfides. Here, we report the mineralogical, textural, and chemical characteristics of nanosulfide‐rich regions identified in Ryugu particles.

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 ...

Iron Isotope Constraints on the Structure of the Early Solar System

The Astrophysical Journal Letters, 2023
The recent advent of nontraditional isotopic systems has revealed that meteorites display a fundamental isotopic dichotomy between noncarbonaceous (NC) and carbonaceous (C) groups, which represent material from the inner and outer solar system ...

Phyllosilicate Infrared Spectral Features as Tracers of Aqueous Alteration in CM Chondrites and Implications for Remote Sensing of Hydrated Asteroids

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract CM (Mighei‐type) carbonaceous chondrites host abundant OH/H2O‐bearing phyllosilicates formed from water‐rock reactions in primitive planetesimals. Their infrared (IR) spectral features resemble those of C‐type asteroids, making laboratory analyses of CMs essential for interpreting asteroid observations.
