Clues for Solar System Formation from Meteorites and their Parent Bodies

Bernard Marty, Katherine R. Bermingham, Larry R. Nittler +1

Understanding the origin of comets requires knowledge of how the Solar System formed from a cloud of dust and gas 4.567 Gyr ago. Here, a review is presented of how the remnants of…

A Pyroxenite Mantle on Mercury? Experimental Insights from Enstatite Chondrite Melting at Pressures up to 5 GPa

Asmaa Boujibar, Kevin Righter, Emmanuel Fontaine +4

Enstatite chondrites (EC) are potential source material for the accretion of Mercury due to their reduced nature and enrichment in volatile elements. Understanding their melting pr…

The Ni isotopic composition of Ryugu reveals a common accretion region for carbonaceous chondrites

Fridolin Spitzer, Thorsten Kleine, Christoph Burkhardt +88

The isotopic compositions of samples returned from Cb-type asteroid Ryugu and Ivuna-type (CI) chondrites are distinct from other carbonaceous chondrites, which has led to the sugge…

Microscale Hydrogen, Carbon, and Nitrogen Isotopic Diversity of Organic Matter in Asteroid Ryugu

Larry R Nittler, Jens Barosch, Katherine Burgess +57

We report the H, C, and N isotopic compositions of microscale (0.2 to 2m) organic matter in samples of asteroid Ryugu and the Orgueil CI carbonaceous chondrite. Three regolith p…

Chromium on Mercury: New results from the MESSENGER X-Ray Spectrometer and implications for the innermost planet's geochemical evolution

Larry R. Nittler, Asmaa Boujibar, Ellen Crapster-Pregont +6

Mercury, the innermost planet, formed under highly reduced conditions, based mainly on surface Fe, S, and Si abundances determined from MESSENGER mission data. The minor element Cr…

Tracing the history of an unusual compound presolar grain from progenitor star to asteroid parent body host

Sheryl A. Singerling, Larry R. Nittler, Jens Barosch +3

We conducted a TEM study of an unusual oxide-silicate composite presolar grain (F2-8) from the unequilibrated ordinary chondrite Semarkona. The presolar composite grain is relative…
