Shortly after the report on NEN 002, a third mass was reported in Agadez, Niger, in mid December 2015 (source B). A request for the weight was answered with the information that ‘two men could not carry it’. Some days later, the iron was transported to a scale in Agadez, weighed, and the mass was given with 202 kg. Estimated longest dimensions are 60 x 40 x 28 cm.
The lenticular meteorite has one slightly convex surface that displays well preserved regmaglypts, and a heavily sculpted and more weathered opposite surface comprising of deep, partly intersecting bowl-shape cavities. Most hollows are of circular or oval shape and measuring 5 – 12 cm across at largest dimensions, while approx. 2 – 5 cm deep.
The mass appears to display a slight degree of orientation, with the convex surface representing the breastside, and the cavernous surface the trailing part. The convex front displays a lead colored pocket measuring ~3 cm across, which is most probably a weathered troilite inclusion still in situ. Corrosion has progressed between the metal groundmass and the inclusion, creating a millimeter sized gap between it and the surrounding metal.
On the opposite surface, near the broader of the narrow edges, acidic corrosion has exposed individual crystallographic planes of the octahedral Widmannstätten pattern. Three orientations of kamacite plates intersecting at approximately 60° angles are visible, indicating that the revealed surface is parallel to an octahedral face (Frost 1965, Ashley 2010, 2016). In addition to providing objective proof of the iron’s meteoritic origin, the revealed crystallographic pattern also gives away the octahedral structure of the meteorite. Based on the photos, the bandwidth cannot be determined, the general dimensions of the structures, however, do not rule out correspondence to those of etched sections of NEN 002.
On the trailing side, NEN 003 is coated with a dark red rusty and partly flaky scale of terrestrial oxides, indicative of a find position completely below the surface. The regmaglypted top surface shows a somewhat brighter oxide coating, presumably controlled by the presence of carbonate deposits. No trace of recent sand abrasion or wind polishing is observed, providing further indication for a complete and prolonged embedding of the meteorite in the sediment.
As in the previous cases, requests for additional find information remained unanswered and no find location other than “found during the search for gold with metal detectors in the Tafassasset” was given.
