Mars Matters Several decades of exploration by orbiting and in situ spacecraft, together with analysis of martian meteorites, have resulted in a wealth of data on the chemical composition of Mars' crust. McSween et al. (p. 736) review these data, which help infer the planet's geological history, discrediting previous ideas suggesting Mars had a wet mantle—similar to that of Earth—and cautioning that martian meteorites are not representative of the planet's crust. The composition of Mars’ crust… Expand
2.10 – Mars
Of all the planets, Mars is the most Earthlike, inviting geochemical comparisons. Geochemical data for Mars are derived from spacecraft remote sensing, surface measurements and Martian meteorites.Expand
Core Formation and Mantle Differentiation on Mars
Geochemical investigation of Martian meteorites (SNC meteorites) yields important constraints on the chemical and geodynamical evolution of Mars. These samples may not be representative of the wholeExpand
Combining meteorites and missions to explore Mars
TLDR
The history inferred from martian meteorites conflicts with results from recent Mars missions, calling into doubt whether the igneous histor y inferred from the meteorites is applicable to Mars as a whole. Expand
Evidence for extremely rapid magma ocean crystallization and crust formation on Mars
TLDR
Concomitant high-precision U–Pb ages and Hf-isotope compositions of ancient zircons from the NWA 7034 Martian meteorite suggest that Mars must have formed its primordial crust extremely swiftly, less than 20 million years after the formation of the Solar System. Expand
The bulk composition of Mars
Abstract An accurate assessment of the bulk chemical composition of Mars is fundamental to understanding planetary accretion, differentiation, mantle evolution, the nature of the igneous parent rocksExpand
Origin and age of the earliest Martian crust from meteorite NWA 7533
TLDR
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. Expand
Mineralogy of the Martian Surface
The past fifteen years of orbital infrared spectroscopy and in situ exploration have led to a new understanding of the composition and history of Mars. Globally, Mars has a basaltic upper crustExpand
GEOCHEMISTRY OF SEDIMENTARY PROCESSES ON MARS
Mars has an extensive, long-lived sedimentary record that is complimentary to the terrestrial record, bearing both first-order similarities and first-order differences. The igneous record is composedExpand
Volcanism on Mars controlled by early oxidation of the upper mantle
Detailed information about the chemical composition and evolution of Mars has been derived principally from the SNC (shergottite–nakhlite–chassignite) meteorites, which are genetically relatedExpand
A Unique Piece of Mars
TLDR
A meteorite with a chemical makeup resembling that of rocks from Mars' Gusev Crater has been identified, and a basaltic breccia unique among known martian meteorites with respect to age, oxygen isotopes, and petrology is found. Expand

TLDR
Observations show that the martian crust, while dominated by basalt, contains a diversity of igneous materials whose range in composition from picritic basalts to granitoids rivals that found on the Earth. Expand
