Combustion and Pyrolysis EA‐IRMS Techniques to Determine the δ2H of Diamonds

Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.

Molecular Asymmetry in Prebiotic Chemistry: An Account from Meteorites

Life, 2016
Carbonaceous Chondrite (CC) meteorites are fragments of asteroids, solar planetesimals that never became large enough to separate matter by their density, like terrestrial planets.

The Maribo CM2 meteorite fall - survival of weak material at high entry speed

, 2019
High entry speed (> 25 km/s) and low density (< 2500 kg/m3) are two factors that lower the chance of a meteoroid to drop meteorites. The 26 g carbonaceous (CM2) meteorite Maribo recovered in Denmark in 2009 was delivered by a superbolide observed by ...

Olivine Microstructure Constraints on Ureilite Parent Body Deformation

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Ureilites are ultramafic achondrites for which the parent body is unknown. Monomict ureilites, consisting primarily of olivine and pyroxene, are thought to represent mantle residues, carrying essential information for their parent body deformation history.

Carbonaceous Chondrite-like Compositions for Proposed Captured Trans-Neptunian Objects Justitia and Pompeja

The Astrophysical Journal Letters
Red spectral slopes (i.e. increasing reflectance with increasing wavelength) and featureless 0.5–2.5 μ m spectra are often associated with the presence of organic material, and there is a sense that the redder the slope, the more organic material is ...

Archives of impact: The politics of craters on Earth

Geographical Research, Volume 64, Issue 2, May 2026.
This paper examines Earth’s 195 confirmed impact craters as archives, exploring their cataloguing and presentation as heritage sites. It argues Western scientific framings using military language and emphasising catastrophe overlook settler colonialism’s violent histories and marginalise indigenous earth‐sky cosmologies.

Heating experiments of the Tagish Lake meteorite: Investigation of the effects of short-term heating on chondritic organics

, 2019
We present in this study the effects of short-term heating on organics in the Tagish Lake meteorite and how the difference in the heating conditions can modify the organic matter (OM) in a way that complicates the interpretation of a parent body’s ...
