» Meteorite: NWA 4965» Meteoritical Bulletin Database
Classification: Achondrite, Brecciated Diogenite
Place/Time: 2017 in Morocco
Mass: 1023g

Physical characteristics: Cut-surfaces of the stones show pale yellowish-green angular clasts (see figure) and have a combined weight of 7020 g. No fusion crust was noted for any of the specimens.
Petrography: (A. Irving and S. Kuehner, UWS) Breccia composed of polycrystalline clasts (? 2 cm) set in a matrix derived from several different diogenite precursors. No basaltic eucrite clasts were observed. The sample is modally dominated by orthopyroxene with subordinate olivine, augite, chromite, silica polymorph, rare calcic plagioclase, troilite, pyrrhotite and kamacite.
Mineral compositions: Orthopyroxene compositions fall into at least three distinct populations (median compositions): Fs17.2Wo1.0, FeO/MnO = 34.4; Fs21.6Wo2.1, FeO/MnO = 29.3; Fs37.2Wo3.5, FeO/MnO = 32.6). Olivine (Fa24.5, FeO/MnO = 50.2).

One of the most beautifull diogenites. Look like lunar meteorite. Fresh, shocked by impact fragments of olivine swim in grey-green matrix.
Slices perfectly polished to the mirror quality.
