From the Meteoritical Bulletin entry on NWA 7397 :
Northwest Africa 7397 (NWA 7397)
Purchased: 2012 Jun
Classification: Martian meteorite (Shergottite)
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, UWS) 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 10 μm across). Olivine contains sparse melt inclusions composed of K-Na-Al-Si-rich glass surrounded by characteristic post-shock radial expansion microfractures.
Classification: Martian (shergottite, poikilitic).
