Impact-driven oxidation of organics explains chondrite shock metamorphism dichotomy [PDF]
Nature CommunicationsShocked meteorites can be used to probe the dynamics of the early Solar system. Carbonaceous chondrites are less shocked than ordinary chondrites, regardless of the degree of aqueous alteration.

Dehydroxylate I formation from the thermal decomposition of serpentine on c-complex asteroids: similarities to carlosturanite [PDF]
Earth, Planets and SpaceDehydroxylate I, a product of the thermal decomposition of serpentine, has been observed in heated carbonaceous chondrite meteorites. To better understand the occurrence of dehydroxylate I on carbonaceous asteroids, we have experimentally heated the ...

Identifying LL Chondrite Near-Earth Asteroids Using LL Chondrite Reflectance Spectra
The Astrophysical Journal LettersMost near-Earth objects are thought to originate from the collisional fragments of the main asteroid belt. One question that remains to be resolved is the proportion of near-Earth objects sampling the core area material of the parent body to the outer ...

YARATKULOVO – A NEW H-CHONDRITE IN THE URALS: MINERALOGICAL DATA [PDF]
Минералогия, 2017 The Yaratkulovo meteorite was found in 2016 in the Argayash district of the Chelyabinsk region. It is a «chondrite breccia», in which the light coarse-grained fragments (primary chondrite) occur in the dark fine-grained matrix (impact assemblages ...

Abiotic sugar enantiomers in the CI carbonaceous chondrite Orgueil [PDF]
Nature CommunicationsThe uneven detection of prebiotic organic compounds in meteorites—where amino acids and nucleobases are commonly identified but sugars remain rare and poorly characterized—limits our understanding of extraterrestrial organic chemistry.

Bubbles to Chondrites-II. Chemical fractionations in chondrites [PDF]
Progress in Earth and Planetary Science, 2021 AbstractWe attempt to develop a possible theory of chemical fractionations in chondrites, that is consistent with various features of chondritic components and current observation of protoplanetary disks (PPD). Combining the 3+2 component fitting calculation that simulates chondrule formation process proposed in paper (I) with additional mixing ...
