[meteorite-list] Iron streams?

[E.P. Grondine]

Hi all - 

I was just contemplating the possibility of a
fragmented iron asteroid making repeated passes by the
Earth, and so I am wondering:

how do the compositions of Meteor Crater (canyon
diablo, odessa?), Campo de Cielo, and Sikote Alin
compare?

I am also wondering, has anybody ran 1950 DA's (hope I
got that name right - think that's the iron asteroid
that's supposed to show up here 800 years from now or
so) orbital elements backward in time?

good hunting,
Ed
