For Sale IconNWA 2975 (Paired) Martain Meteorites for Sale

Location: Reportedly from Algeria--purchased from intermediaries in Morocco.

Found: 2005

Classification: Achondrite, Martian Shergottite (Enriched Mafic)

Description: Petrography: A medium-grained (<3.1 mm greatest dimension) basaltic shergottite that consists of ~57.3 vol% augite and pigeonite pyroxenes, and 38.3 vol% plagioclase (present as shock-formed maskelynite and glasses) with minor opaques (2.7 vol%) and phosphates (1.7 vol%) arranged in a weakly foliated subophitic to granular texture. Accessory phases include ulvöspinel, ilmenite, chlorapatite, merrillite, pyrrhotite, Si-Al-Na-K-rich glasses, and baddeleyite. Vesicular black glass veins (<3 mm in width) and pockets (up to 6 mm) are prominent. Geochemistry: Pigeonite (Fs35.2-57.6Wo12.6-16.5; and augite (Fs27.2-41.5 Wo30.8-35.2) show mottled compositional zoning. Fe-rich margins of pigeonite contain very thin (0.2-0.5 µm) orthopyroxene exsolution lamellae. Maskelynite is compositionally homogeneous An55Or1.8 in contrast to mesostasis maskelynite (An48-60Or9.2) and glasses. Melt inclusions (15-60 µm, longest dimension) in ulvöspinel have rims of Fe-rich pigeonite (Fs73.5Wo5.8), merrillite, and pyrrhotite; cores are Si-Al-K-Na-rich glass. Bulk composition: Calculated average bulk composition based on analyzed phases and their modes of three melt inclusions is: SiO2 = 70.2, Al2O3 = 8.5, TiO2 = 0.8, FeO = 2.1, MnO = 0.2, MgO = 2.35, CaO = 3.5, Na2O = 0.95, K2O = 2. 1, and P2O5 = 2.8 (all wt%) with trace amounts of NiO, CoO, and S. One melt inclusion contains only fayalite (Fa84) mantled around a core of glass (K2O = 6.4, SiO2 = 78; both wt%). From Meteoritical Bulletin Database.

Note: Paired to NWA 2986, NWA 4766, NWA 4783 and perhaps others. Numerous parcels of this meteorite have been sold in Morocco. I don't expect that every parcel will get its own number. Most likely it will be known as NWA 2975 since that is the number associated with the best description. The meteorites listed on this page are paired to these and to NWA 2975.
