Journal ArticleDOI
The Provenances of Asteroids, and Their Contributions to the Volatile Inventories of the Terrestrial Planets
Conel M. O'd. Alexander,R. Bowden,Marilyn L. Fogel,Kieren T. Howard,Kieren T. Howard,Christopher D. K. Herd,Larry R. Nittler +6 more
TL;DR: Hydrogen isotopic analysis of primitive meteorites implicates asteroids as early sources of Earth’s water and argues against an influx of water ice from the outer solar system, which has been invoked to explain the nonsolar oxygen isotopic composition of the inner solar system.
Journal ArticleDOI
Unique Meteorite from Early Amazonian Mars: Water-Rich Basaltic Breccia Northwest Africa 7034
Carl B. Agee,Nicole V. Wilson,Francis M. McCubbin,Karen Ziegler,Victor J. Polyak,Zachary D. Sharp,Yemane Asmerom,M. Nunn,R. Shaheen,Mark H. Thiemens,Andrew Steele,Marilyn L. Fogel,R. Bowden,Mihaela Glamoclija,Zhisheng Zhang,Zhisheng Zhang,Stephen M. Elardo +16 more
TL;DR: Detailed analysis of a meteorite shows that it matches the surface of Mars yet is unlike any other martian meteorite, which suggests the existence of multiple oxygen isotopic reservoirs within Mars.
Journal ArticleDOI
The classification of CM and CR chondrites using bulk H, C and N abundances and isotopic compositions
TL;DR: In this article, the authors used bulk H, C and N elemental and isotopic analyses to classify CM and CR chondrites, and proposed a different classification scheme based on the degree of hydration (wt.% H in water and OH) of a meteorite.
Journal ArticleDOI
A Reduced Organic Carbon Component in Martian Basalts

TL;DR: In this paper, the results of confocal Raman imaging spectroscopy on 11 martian meteorites, spanning about 4.2 billion years of martian history, were reported.
Journal ArticleDOI
Carbonate abundances and isotopic compositions in chondrites
TL;DR: In this article, the authors report the bulk carbonate abundances and C and O isotopic compositions of carbonates in 64 CM chondrites, 14 CR chondites, 2 CI chondrite, LEW 85332 (C2), Kaba (CV3), and Semarkona (LL3.0).
