Meteoritics &Planetary Science, Volume 60, Issue 10, Page 2376-2400, October 2025.Abstract It has been proposed that IIE iron meteorites formed through impact processes on a parent body that was composed of either the H chondrites or a much‐debated fourth ordinary chondrite group, the HH chondrites. To resolve this debate, we have compiled a large dataset for the ordinary chondrites, low‐fayalite ungrouped chondrites, and IIE irons,

, 2017 Copyright © 2017 by The Geochemical Society of Japan. A, B, C, and forsterite-bearing Type B (for classification of CAIs see MacPherson, 2014)) also satisfy this definition, and, as we argue below, provide important constraints on the earliest transient ...

Meteoritics &Planetary Science, Volume 60, Issue 10, Page 2359-2375, October 2025.Abstract We report the first oxygen isotope measurements of tochilinite (δ17O: 11.0 ± 2.1‰, δ18O: 23.5 ± 4.0‰ and Δ17O: −1.1 ± 1.2‰) in a CM chondrite (Winchcombe, lithology C [CM2.2/2.3]). We analyzed type‐I tochilinite‐cronstedtite intergrowths (TCIs)—formed by pseudomorphic replacement of kamacite.

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.

Magnesium phosphate in the Cold Bokkeveld (CM2) carbonaceous chondrite
Meteoritics &Planetary Science, Volume 60, Issue 9, Page 2017-2032, September 2025.Abstract Hydrous Mg‐phosphate was first described from astromaterials in particles returned from the C‐type asteroid Ryugu, and has subsequently been found in samples of the B‐type asteroid Bennu and CI1 carbonaceous chondrites. This phase may have been highly significant as a source of bioessential compounds for early Earth.

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 ...
