Northwest Africa

Purchased 2004 November

Martian meteorite (basaltic shergottite)

A 31.07 g completely crusted stone was purchased by M. Farmer (Farmer).  Classification and mineralogy (J. Wittke and T. Bunch, NAU; A. Irving and S. Kuehner, UWS): olivine-orthopyroxene-phyric basaltic rock composed of euhedral to subhedral olivine phenocrysts and preferentially-oriented, prismatic low-Ca pyroxene phenocrysts in a groundmass of zoned pigeonite (Fs26.4Wo12.4 to Fs34.1Wo12.4) FeO/MnO = 27-31; maskelynite (An66.0-71.0Or0.4), olivine (Fa43.6-47.3) FeO/MnO = 51-58; Ti-chromite (Cr/(Cr+Al) = 0.72-0.79; 9.2-19.8 wt. % TiO2), chromite (Cr/(Cr+Al) = 0.71-0.86; 0.7-2.0 wt. % TiO2), merrillite, ilmenite, ulvöspinel and pyrrhotite.  Olivine phenocrysts are zoned from Fa16.7 cores to Fa43.3 rims, and pyroxene phenocrysts have irregular cores of orthopyroxene (as magnesian as Fs17.9Wo2.4, with ~0.03 wt. % TiO2 and ~0.4 wt. % Al2O3) mantled by pigeonite (Fs25.4Wo4.4 to Fs37.0Wo12.7) with minor subcalcic augite (Fs21.7-24.0Wo 30.8-31.1). It is apparently not terrestrially paired to NWA 1195 and NWA 2046 (Irving et al., 2004b; 2005). Specimens: type specimen, 6.4 g, and one polished thin section, NAU; one polished thin section, UWS; main mass, Anonymous.

LOW TKW - NWA 2626 Martian Shergottite Meteorite .020g!

VERY RARE MATERIAL – Total Known Weight of a Mere 31 Grams!


20 milligram fragment of one of the most interesting Martian meteorites ever found. I only have enough of this material to offer small pieces as most of NWA 2626 has long since been sold out.  With a Total Known Weight (TKW) of only 31 grams, very few collectors will be able to add this rare Shergottite to their collections. No parings have ever been located since it was found in 2004.  This specimen comes with a color identification card identifying it as coming from the world famous Hupé Planetary Collection.
