New NWA 4039 eucrite found in 2005 in Morocco was investigated by scanning electron microscopy. Elemental composition and mineral composition have been analyzed. The composition of feldspars and plagioclases has been determined, and the presence of ilmenite, chromite, troilite and silica confirmed. It was established that the mean elemental composition of NWA 4039 and atomic and molar ratios: Fe/Mn = 31, Na/Al = 0.045, Ca/Al = 0.66 and Mg/Mg+Fe = 31 are typical of eucrites, and two main meteorite minerals have the mean composition: pyroxene En30Fs66Wo4 and plagioclase feldspar An91Ab9. Presence of clinopyroxene pigeonite En37Fs55Wo8 and plagioclase An90Ab10 and An92Ab8 has been
revealed. Mean chemical composition, as well as TiO2 content (0.59 wt%) vs. FeO/MgO ratio (4.11) indicate that NWA 4039 is a non cumulate, basaltic eucrite.
