Unique Meteorite from Early Amazonian Mars: Water-Rich Basaltic Breccia Northwest Africa 7034
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. Expand
Is Mercury a volatile‐rich planet?
] Data returned from the gamma-ray spectrometeronboard the Mercury Surface, Space Environment, Geo-chemistry, and Ranging (MESSENGER) spacecraft havebeen interpreted to say that Mercury is aExpand
A hydrogen-based oxidation mechanism relevant to planetary formation
Article history: It is now generally accepted that the Moon formed by collision of a Mars-sized impactor with the Earth (Hartmann and Davis, 1975), a process termed "the Giant Impact". The oxygenExpand
Hydrous magmatism on Mars: A source of water for the surface and subsurface during the Amazonian
Abstract There is an overwhelming amount of evidence supporting the past existence of abundant flowing water on the martian surface, however the source for this water is less understood. Estimates ofExpand
Inventory of H2O in the ancient Martian regolith from Northwest Africa 7034: The important role of Fe oxides
Water-rich Martian regolith breccia Northwest Africa (NWA) 7034 was analyzed by Fourier transform infrared spectroscopy and transmission electron microscopy to determine the inventory and phaseExpand
Hydrous melting of the martian mantle produced both depleted and enriched shergottites
The search for water in our solar system is one of the primary driving forces for planetary science and exploration because water plays an important role in many geologic processes and is requiredExpand
The Lunar Apatite Paradox
Existing data from the literature is modeled, finding that nominally anhydrous minerals do not sufficiently fractionate H from F and Cl to generate H-rich apatite, which is more consistent with the hydrous magmas of Earth than the otherwise volatile-depleted rocks of the Moon. Expand
Nominally hydrous magmatism on the Moon
The presence of hydroxyl in apatite from a number of different types of lunar rocks indicates that water may be ubiquitous within the lunar interior, potentially as early as the time of lunar formation. Expand
Rapid post-mortem maturation of diatom silica oxygen isotope values
[1] Oxygen isotope values of diatom silica (δ18Odiatom) are increasingly used as paleoclimate proxies; however, the magnitude and timing of post-mortem alteration of δ18Odiatom values has beenExpand
Early accretion of water in the inner solar system from a carbonaceous chondrite–like source
Measurements of the hydrogen isotopic composition of the mineral apatite in eucrite meteorites show that Vesta contains the same hydrogen isotopy composition as that of carbonaceous chondrites, and suggest that Earth received most of its water relatively early from chondrite-like bodies. Expand
