Contribution of the Moon-forming Impactor to the Volatile Inventory in the Bulk Silicate Earth

The Planetary Science Journal
The timing and mechanism by which the present-day inventory of life-essential volatiles hydrogen–carbon–nitrogen–sulfur (H–C–N–S) in the bulk silicate Earth (BSE) was established are debated.

Multiwavelength JWST Observations of (3200) Phaethon Show a Dehydrated Object with an Aqueously Altered Origin

The Planetary Science Journal
We present JWST observations of the near-Earth asteroid (3200) Phaethon using NIRCam, NIRSpec, and MIRI to further investigate the composition of Phaethon’s surface.

Spectral Similarity in the Thermal Infrared between Sulfide-rich Carbonaceous Chondrite Meteorites, Jupiter Trojans, and Other D- and P-type Asteroids

The Planetary Science Journal
Carbonaceous chondrite meteorites, which include the sulfide-rich “Yamato-type” chondrites (CYs), have undergone a complex history of aqueous and thermal alteration and offer crucial insights into early outer solar system conditions.

Mineralogic and petrologic study of the low-temperature minerals in carbonaceous chondrites [PDF]

Samples and petrographic thin sections of the Orgueil, Ivuna, and Alais chondrites were examined by optical, X-ray, and SEM techniques. Mineral species identified as primary vein constituents were epsomite, gypsum, and a calcium-magnesium carbonate ...

Rapid protoplanet formation in the outer Solar System recorded in a dunite from the carbonaceous chondrite reservoir

Communications Earth & Environment
Constraining the timing of accretion, differentiation, and breakup of early-formed protoplanets helps to unravel the Solar System’s evolution. The recent discovery of the oldest crustal material, Erg Chech 002, has provided important constraints on the ...

Molecular Distribution, 13C-Isotope, and Enantiomeric Compositions of Carbonaceous Chondrite Monocarboxylic Acids [PDF]

The watersoluble organic compounds in carbonaceous chondrite meteorites constitute a record of the synthetic reactions occurring at the birth of the solar system and those taking place during parent body alteration and may have been important for the ...
