Found 2001 February 8

Martian meteorite (basaltic shergottite)

A 223.3 g partially crusted stone was found in the same area as Sayh al Uhaymir 005, 008, and 051 by Marc Hauser and Lorenz Moser (Bern) during a search for meteorites. All samples may be paired. Mineralogy and classification (E. Gnos, Institute for Geological Sciences, Bern; B. Hofmann, NMB): a grey-greenish rock with a gabbro-like texture; olivine phenocrysts (average maximum dimension = 1.5 mm) display shock-twinning, mosaicism, and, locally, oxidation; optically clear parts of olivines (Fo_65–69) occur in a finegrained (average maximum grain size = 0.3 mm) groundmass consisting of maskelynite (An_55–64Or_5–9) and pigeonite (En_60–68Wo_7–9) with minor augite, chromite and pyrrhotite; partially recrystallized veins and pockets of shock-melted glass containing vescicles are abundant; x-ray tomography revealed ~0.4 vol% of pores up to 3 mm in size; shock stage, S5; weathering grade, W1; small rusty pockets are Fe-hydroxide replacements of an unknown pre-existing phase. Oxygen isotopes (I. Franchi, OU): δ₁₇O = +2.51·, δ₁₈O = +4.29·, ∆₁₇O = +0.28·. Specimens: all in NMB.
