The phase composition of the El Hammami meteorite was investigated by X-ray, magnetostatic,
Mössbauer effect and environmental scanning electron microscopy methods. Performed investigations
indicated that this meteorite consists of aluminosilicates, olivine (Mg,Fe)2SiO4,
pyroxene (Ca,Mg,Fe)SiO3, kamacite (bcc Fe-Ni alloy) and troilite (FeS). Some inclusions
of Ti and Cr were observed by scanning electron microscopy. The concentration of Ni in kamacite was
determined by comparison of the Mössabauer spectra of Fe-Ni phase in the meteorite with those for
synthetic bcc Fe-Ni alloys (5, 10, 25% Ni).
