Hello Mike, and all,
 
That possibility has already been considered but a study of the isotopes
did prove that this was not the case.
It is one meteorite made up of many fragments.
 
One very well-known meteoriticist called it "a garbage pile"! ;-)
 
I prefer to call it a rubble pile, a loose conglomerate of many disparate
fragments, that shattered upon entry. If you would like to read more about
it, here is a link to the latest abstract written by Professor Bischoff and
soon to be published in MAPS: _http://www.impactika.com/as-maps.pdf_
(http://www.impactika.com/as-maps.pdf)
 
Or you can read an earlier and abridged version on my website:
_http://www.impactika.com/ASitta.doc_ (http://www.impactika.com/ASitta.doc) at the
bottom of the page, after the list of the pieces available.
 
Enjoy.

Hi List,

I have always wondered about the multiple lithologies of this fall.
Is it possible that the multiple lithologies represent more than one
meteorite find? Did the Almahata Sitta ureilite fall into an existing
strewnfield and all of the meteorites got mixed during the recovery?
Has anyone tested the various lithologies to see if they are in fact
related?

Best regards,

MikeG
