Roughness and Angularity of Fragments from Meteorite Disruption Experiments
In this study, we set out to explore the relationship between fracture roughness and sample strength. We analyze 45 fragments of Aba Panu, Allende, and Tamdakht, three meteorites that have been strength-tested to disruption, to determine whether their ...

Hydrous Chondrites under Shock
We examine the shock response of a chondrule-like multicomponent silicate melt enriched with 2 wt% H _2 O, representative of hydrous chondrites, using ab initio molecular dynamics.

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