A single stone of 156 g was found in Morocco between Taouz and Ouzina by a French team under the organization of Bruno Fectay and Carine Bidaut. Analysis of this bencubbinite was conducted at the Museum National d'Histoire Naturelle, Paris, and it was described as being very similar to Bencubbin, Weatherford, and Gujba.

Large clasts of FeNi-metal constitute ~60 vol% of this bencubbinite, while the remainder is composed of olivine and pyroxene silicates having barred to crytocrystalline textures. A plagioclase mesostasis is also present. The metal clasts are composed primarily of kamacite with very rare troilite inclusions, and they exhibit oriented, roughly hemispheric shapes, possibly the result of quenching upon contact with the asteroid surface while still in a plastic state (Perron and Leroux, 2004). The metal structure is consistent with a scenario of having been formed within an impact vapor plume. A detailed discussion of the possible formation models of bencubbinites can be found on the Bencubbin and Isheyevo pages.

An analysis of N, C, and H in NWA 1814 revealed that the highest N abundances are located within tetrataenite mostly associated with sulfides and carbides, with high concentrations occupying metal grain boundaries (Perron and Mostefaoui, 2007). The N, C, and H isotopic values are consistent with those of Bencubbin. The specimen of NWA 1814 shown above is a 1.02 g partial end section. The main mass is shown in the top photo below, while a 23.5 g cut section is shown at the bottom.
