So Different and So Similar Most known meteorites from Mars fit into one class. Agee et al. (p. 780, published online 3 January; see the Perspective by Humayun) describe a meteorite, NWA 7034, which shares some characteristics with other martian meteorites but does not fit within the usual classification. NWA 7034 matches the composition of Mars' surface but is also richer in water than other martian meteorites, and has different oxygen isotope composition, which suggests the existence of… 
New Martian Meteorite is Similar to Typical Martian Crust
Carl Agee, Institute of Meteoritics at the University of New Mexico (UNM), led a team with wide scientific expertise from UNM, the University of California at San Diego, and the Carnegie Institution
Origin and age of the earliest Martian crust from meteorite NWA 7533
Evidence for early crustal differentiation implies that the Martian crust, and its volatile inventory, formed in about the first 100 million years of Martian history, coeval with earliest crust formation on the Moon and the Earth.
Volatile elements in Martian apatite: Insights from new meteorites NWA 7034 and NWA 8159
Measurements of volatile abundances at the martian surface (e.g. H2O, Cl, CO2, CH4) are a priority for the latest generation of martian rovers (Curiosity and ExoMars) due to the astrobiological
Planetary science: A chunk of ancient Mars
It is shown that NWA 7533 has a composition indicative of a highlands breccia, implying that early crustal differentiation on Mars occurred in the first 100 million years of its history, coeval with earliest crust formation on the Moon and the Earth.
A Review of the "Black Beauty" Martian Regolith Breccia and Its Martian Habitability Record.
The regolith breccia Northwest Africa (NWA) 7034 and paired samples are unique meteorite representatives of the martian crust. They are water rich, lithologically varied, and preserve the oldest
Petrography and composition of Martian regolith breccia meteorite Northwest Africa 7475
The Northwest Africa (NWA) 7475 meteorite is one of the several stones of paired regolith breccias from Mars based on petrography, oxygen isotope, mineral compositions, and bulk rock compositions.
Chronology of martian breccia NWA 7034 and the formation of the martian crustal dichotomy
U-Pu/Xe ages are comparable to previously reported Sm-Nd and U-Pb ages obtained from NWA 7034 and confirm an ancient (>4.3 billion years) age for the source lithology.
Insights into the Martian mantle: The age and isotopics of the meteorite fall Tissint
The recent witnessed fall of the meteorite Tissint represents the delivery of a pristine new sample from the surface of Mars. This meteorite provides an unprecedented opportunity to study a variety
New Insights into the Martian Crust and Angrite Parent Body Through Meteorites
Petrologic studies of two new, unique meteorites were conducted in order to characterize the samples and provide insights into their parent bodies. The first sample, Northwest Africa 7034, is the


Tissint Martian Meteorite: A Fresh Look at the Interior, Surface, and Atmosphere of Mars
Tissint (Morocco) is the fifth martian meteorite collected after it was witnessed falling to Earth and shows that it is a depleted picritic shergottite similar to EETA79001A, suggesting that it was ejected from Mars during the same event.

Magmatic carbon in Martian meteorites: attempts to constrain the carbon cycle on Mars
One of the current goals of Martian exploration is to find evidence for extinct (or even extant) life. Carbon (an essential ingredient of life on Earth) is known to occur on Mars as CO2 in the
A review of meteorite evidence for the timing of magmatism and of surface or near-surface liquid water on Mars
[1] There is widespread photogeological evidence for ubiquitous water flowing on the surface of Mars. However, the age of surface and near-surface water cannot be deduced with high precision from
A petrogenetic model for the origin and compositional variation of the martian basaltic meteorites
Abstract— The major element, trace element, and isotopic compositional ranges of the martian basaltic meteorite source regions have been modeled assuming that planetary differentiation resulted from
Elemental Composition of the Martian Crust
Spacecraft data suggest that martian meteorites are not representative of older, more voluminous crust and prompt questions about their use in defining diagnostic geochemical characteristics and in constraining mantle compositional models for Mars.
Linking the Chassigny meteorite and the Martian surface rock Backstay: Insights into igneous crustal differentiation processes on Mars
Abstract— In order to use igneous surface lithologies to constrain Martian mantle characteristics, secondary processes that lead to compositional modification of primary mantle melts must be
The Provenances of Asteroids, and Their Contributions to the Volatile Inventories of the Terrestrial Planets
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.
