Writeup from MB 88:

Bensour

Morocco/Algeria

Found, possible fall, 2002 February 11

Ordinary chondrite (LL6)

Eyewitness accounts from several nomads in the border region of Morocco and Algeria attest to a significant fall of many individual stones on February 11, 2002. However these reports are not detailed. Total weight is estimated to be in excess of 45 kg.  Individual stones (up to 9.2 kg) are very pale grey with a glistening black fusion crust.  Classification and mineralogy (A. Irving and S. Kuehner, UWS):  Very fine grained monomict breccia composed of olivine (Fa31.6, FeO/MnO = 60.0), orthopyroxene (Wo3.5Fs24.3, FeO/MnO = 36.6), clinopyroxene, and sodic plagioclase with subordinate Ni-rich Fe-Ni metal, troilite and chromite.  Sparse chondrules are present.  Oxygen isotopes (D. Rumble, CIW): analyses of two whole rock fragments by laser fluorination gave δ18O = +5.3 ± 0.1, δ17O = +4.0 ± 0.1, Δ17O = +1.20 ± 0.01‰.  Specimens: type specimen, 20 g, and one polished thin section, UWS; 1.5 kg, xHupé, main mass, 9.2 kg, MFarmer.
