[meteorite-list] RE:"Aventura del Monte Meteorite"

[Jason Utas]

Hello All,
After consulting the Handbook of Iron Meteorites by Buchwald, I have begun
to wonder about the identity of this iron a bit more; he states that
troilite inclusions in Sikhote-Alin appear as 1-10mm spherical inclusions,
yet in this specimen, the inclusions (which appear to be troilite -- if
they're graphite, it's not a Sikhote) appear to be much larger and
irregularly shaped.  However, I have some doubts about his description of
the meteorite, as the largest available samples for his inspection weighed
approximately two kilograms.
Does anyone on the list have any pictures of large Sikhote-Alins which they
could send to me for comparison -- or could the owners of any share either
pictures with the list or say whether or not such inclusions are evident
features on his or her specimen?  Google image and regular searches turned
up no relevant hits.
In any case, it *is* an iron meteorite, that much you can be sure of.
Thanks,
Jason
