Ataxites
Some iron meteorites reveal no obvious internal structure upon etching,
and they are called ataxites, for the Greek word for "without
structure". Ataxites consist primarily of nickel-rich taenite, and
kamacite is found only in the form of microscopic lamellae and spindles.
Consequently, ataxites represent the most nickel-rich meteorites known,
and are among the most rare. Among the 50 witnessed iron meteorite falls,
none has been an ataxite; all of the known ataxites are finds.
Paradoxically, the largest meteorite known, Hoba, belongs to this rare
structural class - a strange coincidence that that is hard to reconcile.
