   At least once, the fall site of a meteorite has been
mis-stated. This was in 1992, when Ron Farrell presented
a large ureilite for naming, saying that it was found
in the strewn field of the Nuevo Mercurio chondrite. The
NomCom questioned whether the ureilite might be from the
Nullarbor. I analyzed the sand and soil on the ureilite,
and compared it to sand and soil on a real Nuevo Mercurio,
and on several real Nullarbor stones. The soil on the ureilite
was completely different from Nuevo Mercurio, but nearly
identical to the Nullarbor samples.
   Faced with this uncertainty about its source, the NomCom
named the ureilite Nova 001. Jack Berkley and I wrote a
paper describing the rock, and showing that it was identical
to the ureilite Nullarbor 010. Ron Farrell said that he had
not exported Nova 001 from Australia illegally, and blamed
David New. As far as I know, the matter dropped there.

   So, it is probably possible to find out where a weathered
meteorite fell, at least very broadly. But its a lot of work,
and I doubt anyone would bother for a chondrite.

  Cheers!

Yes, despite being a beginning collector, I feel that just about ALL of the value of meteorites is
in what science can learn about the early history of the solar system (and it's immediate
neighborhood) from them. Collecting them is just an incentive to get those wiley Moroccans out in
the sand looking for meteorites that would not have been found if it were only shallow-pocketed
astronomers out doing research. So, to me, the "value" of a meteorite isn't in WHERE it fell or HOW
MUCH of it fell, but what story a professional study of the meteorite can tell about the evolution
of the universe. Wherther it fell in Utah or Uganda is just a matter of a tiny difference in it's
orbit, and has almost no impact on what can be learned from it. So I would concider inaccurate find
locations for a real meteorite to be of very small concern for the true value of discovering
meteorites-- the science.

Being able to own a chunck of one is just the icing on the cake, not the cake itself.
