Northwest Africa 13106 (NWA 13106)

(Northwest Africa)

Purchased: 2019 May

Classification: Martian meteorite (Shergottite)

History: Purchased in Agadir, Morocco, by Aziz Habibi in May 2019.

Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Intersertal texture with a prominent lattice preferred orientation of maskelynite laths and prismatic clinopyroxene (strongly compositionally zoned). Accessory phases include merrillite, silica polymorph, pyrrhotite, ilmenite (with hematite exsolution lamellae), titanomagnetite (with ulvöspinel exsolution lamellae), baddeleyite, fayalite (in melt inclusions) and anorthoclase (in mesostasis).

Geochemistry: Pigeonite cores (Fs33.0-33.4Wo15.0-14.2, FeO/MnO = 28-29, N = 2), subcalcic augite cores (Fs24.7-29.1Wo24.1-30.0, FeO/MnO = 27-29, N = 3), ferropigeonite rims (Fs70.2-78.3Wo13.4-19.9, FeO/MnO = 39-40, N = 4), subcalcic ferroan augite rim (Fs58.7Wo25.3, FeO/MnO = 38), maskelynite (An55.2-56.1Or1.1-1.7, N = 3), ferropigeonite in mesostasis (Fs84.3Wo10.4, FeO/MnO = 41), anorthoclase in mesostasis (Ab41.4An35.3Or23.3).

Classification: Shergottite (intersertal).

Specimens: 20.5g including one polished thin section at UWB; remainder with Mr. A. Habibi.
