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 …

Séítah is the stratigraphically lowest formation visited by Perseverance in the Jezero crater
floor. We present the data obtained by SuperCam: texture by imagery, chemistry by Laser …

Martian meteorites provide the only direct constraints on the timing of Martian accretion, core
formation, magmatic differentiation, and ongoing volcanism. While many radiogenic isotope …

Poikilitic shergottites make up> 20% of the current martian meteorite collection, with a total of
27 samples. These meteorites are intrusive gabbroic to lherzolitic rocks and represent …

Northwest Africa (NWA) 13669 is a recently found nakhlite and here, we use 2‐D and 3‐D
mineralogy and texture, quantitative textural analysis of pyroxene, bulk rock and mineral …

Shergottites are mafic to ultramafic igneous rocks that represent the majority of known
Martian meteorites. They are subdivided into gabbroic, poikilitic, basaltic, and olivine–phyric …

Gabbroic and microgabbroic shergottites are intrusive igneous rocks on Mars and exhibit a
wide variety of mineralogical and geochemical properties. However, their source reservoirs …

Abstract The 87 Sr/86 Sr isotopic properties of martian meteorites, measured by isolation
and purification of Rb and Sr fractions, have long been used to partially characterise Mars' …

Hydrogen isotopes in the shergottite Martian meteorites are among the most varied in Mars
laboratory samples. By collating results of previous studies on major hydroxyl, deuterium …

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 …
