Meteoritics &Planetary Science, Volume 60, Issue 3, Page 442-463, March 2025.Abstract Cosmic ray exposure (CRE) ages provide information about the parent bodies and source regions of meteorite classes. Cosmogenic noble gases are often used to quantify exposure time scales ranging from tens of ka to hundreds of Ma. The production rate of cosmogenic noble gases is primarily controlled by a meteorite's chemical composition ...

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 464-483, March 2025.Abstract Xenoliths in carbonaceous chondrites include lithologies that are unrepresented in the meteorite record and so are a rich source of information on asteroid diversity. Cold Bokkeveld is a CM2 regolith breccia that contains both hydrous and anhydrous lithic clasts. Here, we describe a hydrous clast with a fine‐grained rim.

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 506-528, March 2025.Abstract JAXA's Hayabusa2 sample return mission visited the volatile‐rich carbonaceous (C‐type) asteroid (162173) Ryugu with the aim of ground‐truthing remote observations, returning a pristine sample from a C‐type asteroid, and strengthening links between asteroids and the meteorite collection. Here, we have conducted a systematic study of coarse (>10

Oxygen Isotope Variations of Basaltic Lavas and Upper Mantle Rocks [PDF]
, 2001 This chapter summarizes the oxygen isotope geochemistry of terrestrial basalts and their mantle sources, including the conceptual framework for interpreting such data and the phenomenology of known variations.

Nanoscale Voltage Enhancement at Cathode Interfaces in Li-ion Batteries
, 2017 Interfaces are ubiquitous in Li-ion battery electrodes, occurring across compositional gradients, regions of multiphase intergrowths, and between electrodes and solid electrolyte interphases or protective coatings. However, the impact of these interfaces

Enrichment of incompatible elements at grain-boundaries of olivine in an olivine-nephelinite.
GEOCHEMICAL JOURNAL, 1986 Variations in the concentrations of trace elements at and near the subgrain-boundaries within olivine phenocrysts in an olivine-nephelinite were inspected with an electron microprobe. The olivine phenocrysts show homogeneous core (Fo85) surrounded by the Fe-richer rim.
