Tindouf 007 is an equilibrated/recrystallized IAB complex iron. It was initially considered a hexahedrite in terms of the structure, and IIAB, IIG or even ungrouped iron based on the elemental composition. It is solely composed of kamacite and no Ni enriched phase was found from the two samples provided for classification. The presence of silicate inclusions, however, indicates affinity to IAB. 

Most individuals are fully or partially oriented. Some are nicely shaped bullets or buttons. All cut and etched pieces show glittering recrystallization patterns.

Recently, Tindouf 007 has been found looking very similar to a unique ungrouped anchondrite NWA 7680. My classifier will analyze silicate inclusions in Tindouf 007 and figure out their relationship.
