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.

Ordinary chondrite NWA 4505 was investigated by confocal Raman micro-spectroscopy. Olivine (Fa0–22), orthopyroxene (Fs6–26), anorthoclase, HT plagioclase, whitlockite, graphite and diamond have been identified. Olivine and orthopyroxene are common and exhibit wide range of Raman shift. Distributions of Raman peaks for olivines and pyroxenes have been analyzed. Narrow, well defined bands of low Ca pyroxenes and olivines indicate on the high structural order and on the high petrologic type of chondrite. The wide range of Fa content in olivine and Fs in pyroxene may indicate that NWA 4505 is an unequilibrated ordinary chondrite.

Ordinary chondrite NWA 4560 was investigated by analytical electron microscopy. Elemental composition and mineral composition have been analyzed. Kamacite, troilite, olivine, orthopyroxene, clinopyroxene, and oligoclase have been identified, and mean composition of meteorite, and composition of olivine, pyroxenes and oligoclase determined. Olivine Fa30–38, orthopyroxene bronzite Fs9–32Wo2–4, clinopyroxenes (pigeonite Fs13–17Wo5–7, as well as augite Fs17Wo22), and oligoclase Ab80An20 have been found in the meteorite. Olivine and pyroxene are common. POP, PO, BO, PP, RP, C, POP, GP and GOP chondrules have been identified. Elemental and mineral composition, atomic ratios and microstructure indicate that NWA 4560 is a type 3.2 ordinary chondrite which belongs to LL group.

New NWA XXX ureilite found in 2006 was investigated by optical microscopy in reflection and in transmission. Olivines, pigeonite, metal veins and dots, and carbon phases have been revealed and their features and distribution studied. Twinning of pigeonite, reduction rims, and poikilitic inclusions of olivine in large pigeonite crystals have been identified and characterized. NWA XXX meteorite belongs to olivine-pigeonite ureilites.

Carbonaceous chondrite NWA 4967 was investigated by confocal Raman micro-spectroscopy. Olivine (Fa0-68), orthopyroxene with high En95-100 and low enstatite content En25-58, clinopyroxene, plagioclase, withlockite, cristobalite, coesite, graphite and diamond have been identified and characterized. Two groups of olivines have been detected: one with high Fo content Fo80-100 and another with relatively high Fa content Fa30–68. Diamond is common and exhibits the wide range of Raman shift between 1298 and 1339 cm–1 with dominant peak at 1332 cm–1 as in the case of terrestrial diamonds. Distributions of Raman peaks for olivines and carbon phases have been analyzed.

Ordinary chondrites DaG 610 and NWA 869, as well as graphite nodules from Canyon Diablo iron meteorites were investigated by confocal Raman microspectroscopy in order to identify extraterrestrial minerals. Olivines, orthopyroxenes (enstatite, bronzite and hyperstene), clinopyroxenes (pigeonite), plagioclase, troilite and various carbon phases, mainly graphite and diamond have been identified and characterized.
