Find, 1956; 1 kg
A stone was found on the loose desert floor. Inspections reveal indistinct chondrules within a largely equilibrated matrix. Compositionally, equilibrated olivine (Fa24) and low Ca-orthopyroxene ('hypersthene') are characteristic of the L-chondrite chemical group. Mineralogically, the meteorite consists primarily of dominant olivine with pyroxene along with minor troilite and Fe-Ni metal. Accessory chromite, copper, graphite, and ilmenite were also reported as part of the Paul Ramdohr (1973) comprehensive review of opaque minerals in stony meteorites.
The main mass is held at the Muséum National d'Histoire Naturelle (Paris).
