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.
