I've been reading up recently on various parent-bodies etc and there are a
bunch of theories out there regarding various irons and stones. One that I
can think of off the top of my head is that some consider the Horse Creek
iron to have a potential origin in common with the Aubrites and/or Enstatite
Chondrites.
Cheers,
Jeff

Subject: Re: [meteorite-list] Any irons/stony-irons linked to known stones?
Hi,
at present, excepted winonaites with IAB irons, no known group of iron is
connected to a group of achondrite.
The situation is slightly different for mesosiderites and pallasites. The
silicate portion of the mesosiderites is certainly linked to HEDs but the
metal
and the silicates are not genetically linked. Concerning pallasites, they
have
been considered to be linked with IIIAB irons, but that's really unlikely
(see
the recent paper in PSRD by Scott...).
Again, it is unlikely that the large impact basin in Vesta displays the
core of
the body...

Selon Melanie Matthews <miss_meteor...@yahoo.ca>:
Are any chondrites and/or achondrites suspected as originating from the
same
parent body as any known irons and stony-irons?
Someone mentioned something asking about the possibility of some irons
coming
from 4 Vesta in another thread, not too long ago...
Cheers
