Ataxites for sale
Some iron meteorites reveal no obvious internal structure upon etching, and they are called ataxites, for the Greek word for "without structure".
Description: 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 rarest. 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.
