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.
Several samples are available for sale.
