Description and terrestrial ages of the Calama Area Meteorite Collection (Atacama Desert, Chile)

Meteoritics &Planetary Science, EarlyView.
Abstract We present a comprehensive study of a meteorite collection from the Atacama Desert (Chile), the driest and most climatically stable desert in the world. This collection includes meteorites from three adjacent Dense Collection Areas (DCAs) in the northern part of the Atacama Desert: Calama, Sierra Gorda, and Chug Chug, referred to as the ...

Spectral Effects of Shock Darkening on Ordinary Chondrite and Howardite, Eucrite, and Diogenite Meteorites

The Planetary Science Journal
Impacts are the most ubiquitous processes on planetary bodies in our solar system. During these impact events, shock waves can deposit enough energy to produce shock-induced darkening in the target material, resulting in an alteration of its spectral ...

Modeling Carbon Outgassing from Chondritic Planetesimals

The Planetary Science Journal
The thermochemical evolution of planetesimals is an underprobed stage of volatile delivery to terrestrial planets during their formation, and may contribute to the volatile depletion of the Earth relative to primitive chondrites.

Quantitative FT-IR Analysis for Chondritic Meteorites: Search for C_60 in Meteorites [PDF]

Journal of Astronomy and Space Sciences, 1998
Infrared absorption spectra of 9 bulk samples and 3 acid residues of meteorites were obtained in the mid-infrared region (4000 ~ 400 cm^(-1)). From the known composition of meteorites studied, the possible absorption modes were investigated.

The use of SEM/EDS method in mineralogical analysis of ordinary chondritic meteorite

Geologija, 2009
The aim of this study was to evaluate the potential of scanning electron microscopy coupled with energy dispersiveX-ray spectroscopy (SEM/EDS) for determination of mineral phases according to their stoichiometry and assessment of mineral composition of ...

Updated Interior Structure of Callisto From a Reanalysis of Galileo Data

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract The internal structure of Callisto has been a long‐standing question since the Galileo mission. Previous analyses suggested a largely undifferentiated interior. We present an updated interior structure for Callisto derived from a reanalysis of Galileo's Doppler tracking data using new signal processing techniques.

Tracing Continental Basalt Sources and Mantle Processes Using Fe Stable Isotopes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract Iron (Fe) isotopes have emerged as powerful tracers of mantle source heterogeneity and melting processes, yet the mechanisms producing heavy Fe isotope signatures (high δ57Fe values) in intraplate basalts remain debated. Competing interpretations include partial melting of recycled pyroxenite domains versus carbonate‐induced oxidation of a ...

Testing the Bus–DeMeo Asteroid Taxonomy Using Meteorite Spectra

The Planetary Science Journal
The most widely used method to spectrally classify asteroids is the Bus–DeMeo taxonomy. To test how well the Bus–DeMeo taxonomy groups asteroids on the basis of their mineralogy, we have classified ∼1500 meteorite spectra using this Bus–DeMeo system ...
