NWA 7397 (Paired) Martain Meteorites for Sale
Location: Reportedly Found near Smara, Morocco.
Found: 2012
Classification: Achondrite, Martian Shergottite (Enriched Permafic Poikilitic)
Description (NWA 7397): History: Found near Smara, Morocco and purchased by Darryl Pitt and David Gheesling from a dealer in Zagora, Morocco in 2012 June. Physical characteristics: A 2130 g, partially covered in fusion crust. Interior larger ovoid crystals in a finer grained matrix. Petrography: (A. Irving and S. Kuehner) Large oikocrysts (up to 1.5 cm across) of low-Ca pyroxene enclose multiple chadacrysts of olivine and Cr-rich chromite. Relatively equigranular domains between oikocrysts are composed of low-Ca and high-Ca pyroxene (showing very limited compositional zoning), maskleynite and olivine with accessory merrillite, Ti-chromite, pyrrhotite and ilmenite (with associated grains of baddeleyite up to 10μm across). Olivine contains sparse melt inclusions composed of K-Na-Al-Si-rich glass surrounded by characteristic post-shock radial expansion microfractures. Geochemistry: Olivine (Fa38.9-40.7; FeO/MnO = 47-54), orthopyroxene (Fs30.3Wo3.3; FeO/MnO = 36), pigeonite (Fs25.1-27.6Wo6.6-10.0; FeO/MnO = 28-33), subcalcic augite (Fs17.0-19.0Wo35.1-35.4; FeO/MnO = 22-25). Bulk trace element composition (G. Chen, UAb): analysis by ICP-MS of clean wire-saw cutting dust gave (in ppm) La 1.66, Ce 4.48, Nd 2.93, Sm 1.13, Eu 0.3, Gd 1.59, Dy 1.95, Yb 1.02, Lu 0.14, Hf 1.66, Th 1.15, Rb 2.89, Sr 33.6.
Comment: The specimens for sale here were puchased as a NWA 7397 pair from the same reputable source that sold the original NWA 7397. Thus they are believed on good authority to be paired. This meteorite has not been classified. When these specimens are found, the finders break down the pieces into small parcels and sell them to many dealers. After a number of parcels have been classified, further classification becomes redundant. Moreover, classifying and submitting a curated sample of multiple small parcels becomes prohibitively expensive for the sellers and raises the prices of offerings.
