Late delivery of exotic chromium to the crust of Mars by water-rich carbonaceous asteroids
The terrestrial planets endured a phase of bombardment following their accretion, but the
nature of this late accreted material is debated, preventing a full understanding of the origin …

Chondritic late accretion to Mars and the nature of shergottite reservoirs
Mars is considered to have formed as a planetary embryo that experienced extensive
differentiation early in its history. Shergottite meteorites preserve evidence for this history …

Highly siderophile elements in shergottite sulfides and the sulfur content of the martian mantle
Shergottite meteorites are ultramafic to mafic igneous rocks derived from partial melting of
distinct regions of the martian mantle. As such, they trace magmatic processes, including …

Chalcophile-siderophile element systematics of hydrothermal pyrite from martian regolith breccia NWA 7533
Unlike other martian meteorites studied so far, Martian regolith breccia NWA 7533 and
paired meteorites that have sampled 4.4 Ga-old impact lithologies show only sulfides of …

Concept and design of martian far-IR ORE spectrometer (MIRORES)
Sulfide ores are a major source of noble (Au, Ag, and Pt) and base (Cu, Pb, Zn, Sn, Co, Ni,
etc.) metals and will, therefore, be vital for the self-sustainment of future Mars colonies …

High‐precision determination of gold mass fractions in geological reference materials by internal standardisation
Determination of gold abundances in natural rock is critical for applications, but very
challenging. Here, we report a method for determining gold with a very low mass fraction (> …

The sulfur budget and sulfur isotopic composition of Martian regolith breccia NWA 7533
The sulfur isotope budget of Martian regolith breccia (NWA 7533) has been addressed from
conventional fluorination bulk rock analyses and ion microprobe in situ analyses. The bulk …

Petrogenesis of martian sulfides in the Chassigny meteorite
The Chassigny meteorite, a martian dunite, contains trace amounts (0.005 vol%) of Fe-Ni
sulfides, which were studied from two polished mounts in reflected light microscopy …
