    Microscopic studies of Al Haggounia 001 meteorite
    (Wydawnictwo Politechniki Łódzkiej, 2011) Szurgot, Marian; Polański, Krzysztof; Kosiński, Janusz
    Elemental composition, mineral composition and microstructure of Al Haggounia 001 meteorite found in 2006 were studied by analytical electron microscopy. It was established that orthopyroxene dominated by enstatite (En89-S2Fs16-10Wo1-2), sodic plagioclase (Ab81-84An10-12Or4-5), graphite, and oxidized kamacite identified in the sample represent extraterrestrial minerals typical of enstatite meteorites. Chemical and mineral composition, and texture confirm that Al Haggounia is EL chondrite rather than aubrite, and terrestrial weathering significantly changed primary meteorite minerals.e
