NWA 1465, Anomalous CV3 Meteorite, Endcut, 5.84g

NWA 1465 was first recovered out of the desert in Western Sahara in 2001. Approx. 3 kilograms of fusion crusted stones were found and samples were classified as a shocked CV3 chondrite. It has a wealth of chondrules and CAI inclusions set into a dark fine-grained groundmass. There are also clasts of darker material whose oxygen isotope range measure outside that of the host rock, and thus the official classification is CV3 anomalous. A modest amount of this material made it onto the collector market many years ago and is rarely seen on the market now.

The specimen being offered here is a professionally-prepared endcut that is polished on one side. It weighs 5.84 grams.

Found 2001

Carbonaceous chondrite (CV3 anomalous)

Many pieces totalling 3000 g and mostly covered with fusion crust were found in 2001 by an anonymous finder in the Western Saharan desert. Classification and mineralogy (A. Greshake, MNB and M. Kurz, Kurz): a type 3 carbonaceous chondrite with chondrules, mineral fragments, and refractory objects in a compact anhydrous matrix of Fe-rich olivine, Ca-rich pyroxene, enstatite, forsterite, troilite, magnetite, FeNi-metal, and weathering products; 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) oxygen isotope composition of dark material, not in equilibrium with the host meteorite. Shock stage, S4; degree of weathering, W3. Specimens: type specimen, 21.8 g, and one polished thin section, MNB; main mass with anonymous finder.
