NWA 1465 - The Anomalous CV3 Meteorite
144 gram individual
NWA 1465
Classification: CV3 anomalous
Year found: 2001
Country: Northwest Africa
TKW: 10.5 kg
Many pieces totaling 3000g and mostly covered with fusion crust were found in 2001 by an anonymous finder in the Western Saharan desert. Shortly afterwards a 7.5kg mass was found.
Classification and mineralogy (A. Greshake, MNBKurz):
a type 3 carbonaceous chondrite with chondrules, mineral fragments, and refractory objects in a compact anhydrous matrix of Fe-rich olivine (Fa43-57.6), Ca-rich pyroxene, enstatite, forsterite, troilite, magnetite, FeNi-metal, and weathering products; olivine, Fa5.5 (range Fa0.4-41.9); pyroxene, Fs2.8 (range Fs0.8-5.5); shows a strong foliation defined by flattened chondrules and refractory objects; the sample contains cm-sized Ca,Al-rich inclusions and large inclusions of dark material (Greshake et al., 2003); oxygen isotope composition of the bulk meteorite (R. Clayton and T. Mayeda, UChi): δ18O = 4.89‰, δ17O = 0.71‰; oxygen isotope composition of dark material, δ18O = 13.08‰, δ17O = 5.83‰., is not in equilibrium with the host meteorite. Shock stage, S4; degree of weathering, W3.
I completed a trade for several stones from this very rare and studied meteorite. This is one of only four meteorites classified as CV3-an and the only one available to collectors.
