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…

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 whole

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.

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.

What Martian Meteorites Reveal About the Interior and Surface of Mars

Martian meteorites are the only direct samples from Mars, thus far. Currently, there are a total of 262 individual samples originating from at least 11 ejection events. Geochemical analyses, through

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.

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 crust

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 related

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.

The early development of Mars is of enormous interest, not just in its own right, but also because it provides unique insights into the earliest history of the Earth, a planet whose origins have been

Evidence for magmatic evolution and diversity on Mars from infrared observations

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.
