Hi List!

According to MetBull: "A single 83 kg individual completely covered with
well developed regmaglypts" was found. Don't know if it was examined too.

Best wishes

Ingo

But is there a finest octahedrite among the chemical IAB/IIICD-complex....?
And are there coarsest octahedrites to be found among the IVAs?

I think, it's quite reasonable, not to give a structural type at that point
of time for the Egypt iron, if there were only shrapnels found, respectively
analyzed.
Shrapnels by their nature are always ataxitic.

Or was meanwhile a not so damaged individual found and examined?

Best!
Martin

"Ataxite" is a structural term, like octahedrite and hexahedrite.
Modern classification of iron meteorites is based on the chemical group,
which can tell you something about the parent asteroid. The structural
classification is quasi-independent of the chemical classification,
inasmuch as members of each structural group can belong to multiple
chemical groups. So "ataxite" has not been replaced with "iron,
ungrouped." Both are correct.

When I used to edit MetBull, the heading on the description of this
meteorite would have said "Iron, ataxite (ungrouped)", but other editors
have abandoned this.
