Ordinary chondrite, veined (L6; S2)
Fell, 9 December 1865, 11-12 hrs; 50 kg

Two stones of approximately equal mass fell approximately 5 km apart in regions controlled by the Senhadja and Ouled Sidi Salem peoples. Numerous photographs reveal meteorites with irregularly textured, multicolored components. Larger angular and rounded chondrules and fragments are set within a usually lighter and greyish matrix. In some polished sections, darker fragments appear to be rimmed by mildly oxidized material. The largely equilibrated matrix contains indistinct chondrules as well as numerous very small grains of Fe-Ni metal and troilite. Compositionally, total iron (21.6 wt%Fe) along with olivine (Fa24.3) and low Ca-orthopyroxene (Fs21) are characteristic of the L-chondrite geochemical group. The largely equilibrated primary silicates and usually indistinct chondrules are characteristic of the L6 petrologic type. Mineralogically the meteorite consists primarily of dominant olivine and pyroxene accompanied by minor plagioclase, troilite, and Fe-Ni metal. Accessory chromite, copper, diopside, ilmenite, merrillite, and minor sulfides are among reported phases. Veins and abundant maskelynite are indicative of significant preterrestrial shocks (shock level = S2).

The L-group of ordinary chondrites (relatively low in total iron) are the largest group of classified witnessed meteorite falls and account for ~45% of all well-classified meteorite falls. The L6 petrologic type accounting for ~ 70% of the L-group. 272 meteorite falls had been classified exactly as 'L6' chondrites by early June 2017.

The main mass has been kept at the Muséum d'Histoire Naturelle (MHN) in Paris.
