NWA 5480 Olivine Diogenite Meteorites for Sale
Location: Northwest Africa, exact location unknown.
Found: 2008.
Type: Diogenite; Olivine diogenite
Description: A fresh, dense, heterogeneous rock. It consists of 57 vol.% olivine (Fa30.2, FeO/MnO = 46.6) and 42 vol.% orthopyroxene (Fs24.8Wo1.8, FeO/MnO = 25.6) with minor chromite [Cr/(Cr+Al) = 0.828, TiO2 = 0.71 wt.%], troilite and Ni-free metal; Plagioclase is absent; Olivine occurs as brown polygranular clusters and as tiny rounded grains within larger yellow-green oikocrysts of orthopyroxene; most chromite is very fine grained but sporadic, larger grains are up to 1.5 cm across. At hand specimen scales, olivine is seen to be distributed in schlieren-like bands, possibly consistent with magmatic or plastic flow within a stress field. We suggest that NWA 5480 may be a sample of the Vestan mantle, representing a partial melting residue that has experienced recrystallization and plastic deformation at relatively high temperatures and pressures.
